A cowboy, his horse and his dog were captured by hostile Indians.
This wasn't really a problem for the animals as the Indians can always use
them, but the cowboy is informed that he will be burned at the stake the
following sunrise. That evening, the Indian chief tells the cowboy that
he can one last wish, within reason, of course, before meeting his fate
the following morning. The cowboy replies that all he really wants is to
see his faithful dog, Rex, one last time. When the dog is brought by the
Indians, the cowboy hugs his companion and whispers something into his ear.
At once the dog runs off over the hill. Amazingly enough, a few hours later,
he returns, accompanied by some two dozen prostitutes from a nearby town.
Needless to say, the braves are delighted and as a reward offer the cowboy
his dog to keep him company through the rest of the night. When the dog is
brought forth the cowboy again runs his hand over Rex's head and then bends
down to whisper into his ear: "This may be my last chance, Rex, so get it
right this time -- go into town and get the posse!"
