A farmer decided it was time to get a new rooster for
his hens.  The current rooster was still doing a good
job, but he was getting on in years and the farmer
figured getting a new rooster couldn't hurt anything. 
So he buys a young cock from the local rooster
emporium and turns him loose in the barnyard.

Well, the old rooster sees the young one strutting
around and gets a little worried.  "So, they are trying to
replace me," he thinks.  
He walks up to the new bird and says, "So you're the
new stud in town?  I bet you think you're hotstuff, don't
you?  Well, I'm not ready for the chopping block yet. 
I'm better than you are, and I'll prove it.  I challenge you
to a race around that hen house.  We'll run around it
ten times and whoever finishes first gets to have all
the hens for himself."

"You're on, old man.  I'll even give you a head start of
half a lap, and I'l still win easily."
So the two roosters go over to the hen house to start
the race, and all the hens gather around to watch.  The
race begins, and all the hens are cheering the roosters
on.  After the first lap, the older rooster still has his
lead.  But after the second lap, the young stud starts to
catch up.  By the third and fourth lap the old rooster's
lead gets smaller and smaller, until he's just barely in
front of the young rooster on only the fifth lap.

By now the farmer has heard all the ruckus.  He runs
into the house to get his shotgun, thinking there's a fox
in the henhouse.  When he gets there, he sees the
two roosters running around the hen house, the old
rooster just barely in the lead.  He immediately raises
his shotgun and blows the young rooster away.
"Damn, that's the third gay rooster I've bought this
month."
