- I have some times read a riddle where there are two brothers (or
- such) positioned at two gates, one to pleasure (heaven, whatever),
- one to hell. You want to find out which is which, and may ask only
- one of them one question. The usual solution is
- <here comes the spoiler>
-
- What would your brother say if i asked him whether the left door was
- the right one (I mean rather, the pleasurable one :]). If he says
- yes, it is not, and if he say no, it is. (think about it)
-
- The solution I propose is more subtle and in my opinion more appealing:
- <next spoiler>
-
- What would you say if I asked you whether the left door leads to pleasure?
-
- And for yes, enter left, for no right.
-
- What version do you prefer?
