- Contra-reality puzzles, or, "That's not the way it works!"
-
- 2.10. A man is sitting in a train compartment. He sees a three-
- fingered hand through the compartment window, in the hallway of the
- train. He opens the compartment door and shoots the person with the
- three-fingered hand, but he goes free. (Michael Bernstein)
- 2.10. He's with a policeman, who's taking him to jail, and he uses the
- policeman's gun. He was convicted of his wife's murder; she had framed
- him for it somehow, involving cutting off two of her own fingers and
- mailing them to the police. Since he had already been convicted of her
- murder, he couldn't be tried twice for the same crime, and since he
- obviously hadn't actually been guilty before, he's set free. The main
- problem with this question is that as far as I know, that's NOT how the
- "double jeopardy" law works, and so it couldn't happen in real life.
- Nonetheless, it's a neat setup.

- By Cheryl Balbes:
- Situation:
- A woman sees a man on a train eating an orange. She shoots and kills him. She
- is arrested and known to be sane and guilty but does not go to jail.
- Solution:
- The man and the woman were married. It was a terrible marriage - so terrible
- that he wanted revenge for it. So he cut off three of his fingers and burned
- down the house. The police arrived and arrested the woman for murder of her
- husband, citing the fingers as evidence of his death. She was tried and
- convicted and went to jail for most of her life. When she finally got out, she
- took a train ride and saw a man eating an orange. When he used the orange
- peeler, she could see that he was missing three fingers so she knew he was her
- husband. For ruining her life, she took out a gun and shot him dead. She was
- arrested and known to be guilty, but could not go to jail again for the same
- crime.
- Dan Cory]
- [Ian Collier has a slightly variant answer:
- 30 years ago, the man and the woman (his wife) attempted to
- defraud the insurance company by faking her death. However he was found
- guilty of murdering his wife and given a long prison sentence (his wife
- remained hidden and made no attempt to prevent the conviction). The man,
- having just been freed from prison, summons his wife from a far city
- and shoots her. He is not punished, because he has already served the
- sentence.]
-
- 2.61. A man ran into a fire, and lived. A man stayed where there was
- no fire, and died. (Eric Wang original)
- 2.61. The two men were computer programmers working in a small room
- protected by a halon gas fire extinguisher system, when a fire broke out
- in an adjoining room. One of the programmers ran through the fire and
- escaped with only minor burns. The other one stayed in the room until
- the building's fire extinguishers kicked in, and died of oxygen
- starvation when the halon gas combined with all of the oxygen in the
- room. I'm told by Rolf Wilson that this really isn't how halon gas
- extinguishers work, so this puzzle should unfortunately be removed from
- the list.
-
- 2.50. The pope is giving a speech. A man in the audience shoots the
- mayor who is behind the pope. (PRO)
- 2.50. The pope has returned to the village where he began his
- priesthood fifty years earlier. He was late for the ceremony, so the
- mayor spoke first; he claimed to be the first person to give confession
- to the pope, fifty years earlier. When the pope arrived, he related
- that the first confession he had heard was that of the murder of a young
- woman. The man in the audience had a sister who was murdered at that
- time. The sanctity of the confessional is conveniently ignored.

- In article <64023@netnews.upenn.edu>, weemba@libra (Matthew P Wiener) writes:
- >Here's [one] I made up years ago: "She stopped having sex. She died."
- A woman was a hemophiliac. She stayed pregnant whenever possible. When
- she stopped having sex, she had her first period, and bled to death.
- [jeh comments: there was a lot of debate on the Net about this, most of
- which tended to conclude that (a) menstrual fluid isn't blood; (b) most
- of the few female hemophiliacs die at birth; and (c) terminating a
- pregnancy in any conceivable (heh) way is likely to result in too much
- blood loss.]
-
- 1.37. A holy man is dead in a room. (Perry Deess original)
- 1.37. The man is a Moslem. He was caught stealing, and so his right
- hand was cut off. However, he's very devout, and thus isn't allowed
- to eat using his left hand; so he starved to death. It could be
- argued that this isn't very realistic; he could've gotten someone to
- feed him, or somehow eaten without using his hands at all. And I
- don't know if those rules of Islam really interact that way. Any real
- info would be appreciated.
- [Ivan A Derzhanski writes:
- They are supposed to use their left hand. There is more than one tale
- in the _Arabian Nights_ about someone who has lost his right hand,
- typically as a punishment for theft (and typically unjustly). He
- conceals this fact (long sleeves and all that), until he is served a
- meal and the storyteller sees him eating with his left hand, something
- which is not exactly taboo, but is not the done thing either.
- Note that the punishment for theft is known to be loss of the right
- hand, not death by starvation.
- I would be more interested to know what a Hindu would do. Those
- people are much more careful about what is to be done with which hand.
- And, of course, there are many ways to lose a hand.]

-
- Clocks, calendars, money, and other numerical trivia:
-
- 2.15. Two people are talking long distance on the phone; one is in an
- East-Coast state, the other is in a West-Coast state. The first asks
- the other "What time is it?", hears the answer, and says, "That's funny.
- It's the same time here!" (EMS)
- 2.15. One is in Eastern Oregon (in Mountain time), the other in
- Western Florida (in Central time), and it's daylight-savings changeover
- day at 1:30 AM.
- 2.15a. Variant answer: The east-coast state is in the USA, on Eastern
- Daylight time. The west-coast state is Western Australia. There's a
- twelve-hour time difference, so it's 8 o'clock in both places. (from
- Tim Lambert.)
-
- 2.19. A woman goes into a convenience store to buy a can of Coke. She
- pays for it with a $20 bill and receives $22 in change. (MI; partial MB
- wording)
- 2.19. It's in Canada; she pays in American money and receives change in
- Canadian money. Mark Brader points out that the amount of change can
- vary wildly depending on the price of the drink as well as both the
- official exchange rate and the actual exchange rate given.
-
- 2.20. A newspaper reported that Jacques Dubois finished first in the
- walking race held in Paris. The number of miles he walked was given
- as 62,137. The article was not in error. (AR, quoting Richard Fowell;
- MB wording)
- 2.20. The comma, in European numbers, is used the same way Americans
- use a decimal point. The man thus (Americans would say) walked 62.137
- miles, or 100 km. Mark Brader points out that no newspaper in a country
- which uses the decimal comma would report the distance in miles; if
- anyone can think of a way around this problem, let me know. One
- possibility is to say that he walked 42,551 km (or whatever the actual
- length of a marathon is); but I don't know whether there are such things
- as walking marathons, or whether they'd be the same length in Europe as
- in America.

- From: SCOTT MATTHEWS <SDM119@psuvm.psu.edu>
- A man goes to a hardware store to buy a certain item. He asks the salesman
- how much this item costs to which he answers, "They are 3 for $1.00." The man
- say, "Okay I'll take 100," to which the salesman correctly replies, "That will
- be $1.00." The man pays $1.00 and leaves satisfied. What is the item.
- [A: house numbers.]
-
- >"A man, his son, and his grandson had their first birthday together."
- (Matthew P Wiener original)
- David Grabiner's answer:
- Sweden had no leap-year days from 1748 to 1788 in order to catch up with
- the Gregorian calendar without creating excessive trouble. (In many
- other countries, people found that their loans suddenly became due
- eleven days earlier.)
- Thus, the grandfather was born in Sweden on February 29, 1744; the
- other two were born outside Sweden on February 29, 1768 and 1788,
- and returned to Sweden before their fourth birthdays.
- [jeh comments: this is, as Matt said in his original posting, an
- obscure-calendar puzzle; and the net indicated that the calendar
- story may not be true anyway.]
-
- -----------------------------------------
-
- Just too weird and/or random and/or silly for me:
-
- 2.17. A woman walks up to a door and knocks. Another woman answers the
- door. The woman outside kills the woman inside. (GH)
- 2.17. The woman outside is a psychotic librarian. The woman inside has
- an extremely overdue book.
- 2.17a. Variant answer: The woman outside is married and lived at the
- home in question. She misplaced her key, and the door was answered by
- her husband's lover. Though this answer would allow the question to be
- in section 1, it's really a much-less-interesting version of #1.15, and
- it seems to me that it would be a fairly obvious answer.
-
- 2.59. A man is lying dead in a pool of blood and glass. (PRO)
- 2.59. The man caught a large fish and was so excited he went to a phone
- booth to call his wife. In trying to describe the size of the fish, he
- said, "It was THIS big!" and stretched his arms wide to indicate its
- length. His arms went through the sides of the phone booth, his wrists
- were sliced by broken glass, and he bled to death.
- [Variant from Bernd Wechner:
- A man makes a telephone call and dies.
- Answer: The man was ringing his wife, and learned from her that he had
- won the lottery. In jumping for joy he broke through the glass wall
- of the telephone booth and cut his wrists whereupon he bled to death.]
-
- 2.60. The seals came up to do their show but immediately dove back into
- the water. (PRO)
- 2.60. The seals were frightened by an audience of nuns, who, to the
- seals, looked like a herd of killer whales.
-
- 2.58. A raft carrying passengers took a trip down a river. None of the
- passengers made it home alive. (CR; partial JM wording)
- 2.58. The raft was floating down the Amazon river when it floated under
- a big tree. A snake was hanging down out of the tree, so the people
- pushed the entire raft away from the tree, where it capsized. The
- passengers were then eaten by piranha.
-
- -----------------------------------------
-
- Confusing the map with the territory, or, call by reference:
-
- 2.22. In his own home a man watches as a woman dies, yet does nothing
- to save her. (MN)
- 2.22. He saw it happening on TV.
-
- 2.39. King Henry VIII is lying at the bottom of the stairs with a gash
- across his face. (PRO)
- 2.39. It is a painting of Henry VIII.
-
- 2.40. A man travels to twenty countries and stays in each country for a
- month. During this time he never sees the light of day. (PRO)
- 2.40. The man is a mummy, on tour to different museums throughout the
- world.
-
- [note similarity of type to "ship at bottom of sea" and "husband who'd
- blown his brains out."]
-
- -----------------------------------------
-
- How to prove your audience are sexists:
-
- 2.48. A boy and his father are injured in a car accident. Both are
- taken to a hospital. The father dies at arrival, but the boy lives
- and is taken to surgery. A grey-haired, bespectacled surgeon looks at
- the boy and says, "I cannot operate on this boy -- he's my son." (JV)
- 2.48. The surgeon is the boy's mother. As with #2.45, #2.46, and
- #2.47, I've frequently heard this as presented as a riddle; the
- attributions for these indicate the first person to tell them to me as
- mystery questions.
-
- 2.49. A husband coming home hears his wife call "Bill, don't kill me!".
- He walks in and finds his wife dead. Inside are a postman, a doctor,
- and a lawyer, none of whom the husband knows. The husband immediately
- realizes the postman killed his wife. (EMS; partial JM wording)
- 2.49. The postman is a man. The doctor and lawyer are women.
-
- -----------------------------------------
-
- Need some work:
-
- 2.56. She said "I love you," and died. (EMS)
- 2.56. She was a circus performer who performed rope tricks. During one
- of them, she hung from the ceiling holding only a rope in her mouth.
- The other end of the rope was held by her husband. There's no
- motivation given for her choosing to do something so stupid; if anyone
- wants to twiddle this into a more reasonable question, please do.
-
- Q. A woman gets up, drives to town, buys a gun, and shoots her husband.
- A. The woman suspects her husband of cheating on her. She notes the mileage
- on the car each day. The previous night, hubby worked late at the
- office, but the mileage on the car is far greater than can be
- accounted for. (from Simon Travaglia)
- [jeh comments: This last could make a really nice puzzle, but has too many
- plotholes as it stands. Rework it sometime.]
-
- > >"He opens his mouth and she dies." (Ivan A Derzhanski)
- The male acrobat
- hangs from the ceiling and holds the female acrobat by his teeth. He
- drops her, and she breaks her spine.
- [jeh comments: again, this needs more of a real story for me to accept
- it.]
-
- > >"He comes home, undresses, turns the light off and goes to bed. After a few
- > >minutes he springs up and says, `There's a corpse under my bed!'"
- (Ivan A Derzhanski)
- He hears a watch
- tick under the bed. Why the watch has to be on the hand of someone
- (and if it is, he is obviously dead, because his breath is not heard)
- is left to the guessers' discretion.
- [jeh comments: see previous comment.]
-
- 2.34. A man is holding a box. Though he cannot see into it, he knows
- what's inside. (Eric Stephan original)
- 2.34. He's allergic to whatever's inside the box.
- [jeh comments: how is this different from just being able to smell it?]
-
- -----------------------------------------
-
- Miscellaneous others:

- up. When she answered it the caller hung up. The caller felt better.
- (Sasan Soltani)
- 2.24. It was a husband calling from overseas to see that his wife
- arrived home all right. Hanging up before three seconds elapse results
- in no charge to the calling party. He could not call person-to-person
- because the local operators did not speak English.
-
- 2.27. A man called to a waiter in a restaurant, "There's a fly in my
- tea!" "I will bring you a fresh cup of tea," said the waiter. After a
- few moments, the man called out, "This is the same cup of tea!" How did
- he know? (PRO)
- 2.27. The man had already sugared his tea before sending it back.

- 2.44. The dish is a satellite dish.
-
- 2.45. An Arab sheikh tells his two sons that are to race their camels
- to a distant city to see who will inherit his fortune. The one whose

- Soltani)
- 2.46. The children are two of a set of triplets.
- [jeh wonders: is this fundamentally different from the people
- crowding under an umbrella or the black-painted town? Should all
- three be together on one list or the other?]
-
- 2.47. A couple will build a square house. In each wall they'll have a
- window, and each window will face north. (Sasan Soltani)
- 2.47. The house is at the south pole. This is much the same question
- as the age-old riddle asking what color a certain dead bear is.
-
- The man who built it didn't use it, the man who used it didn't want it,

-
- 1.35. A policeman follows a burglar into a bar. When he enters the bar

- 1.35. Both men were wearing glasses. The burglar, however, was wearing
- photosensitive sunglasses; the policeman noticed them changing shade and
- realized the man must have just entered.

- one above is presented to a group of players, who must then try to find
- out more about the situation by asking further questions. The person who
- initially presented the situation can only answer "yes" or "no" to
- questions (or occasionally "irrelevant" or "doesn't matter").
-
- My list has been divided into two sections. Section 1 consists of
- situation puzzles which are set in a realistic world; the situations could
- all actually occur. Section 2 consists of puzzles which involve double
- meanings for one or more words and those which could not possibly take
- place in reality as we know it, plus a few miscellaneous others.
-
- See the end of the list for more notes and comments.
