The goat at the base of the hill
San Jose Guy is new to town and steps in the local pub for a drink. After a couple drinks he decides to ask the bartender
"Where are the women around here? I need to get laid."
The bartender says "You're not gonna find any around here, but there is a goat at the base of the hill..."
"Fuck off!" San Jose Guy says "I'm not that drunk!"
So a couple hours later he's at home entertaining the idea of the goat, when he decides to go through with it and fuck the goat.
The next day he goes back into the pub to find the bartender
"Hey thanks for the tip! I fucked the goat and it was surprisingly human like. But I feel bad for that thing, all these men in town having a go with it."
The bartender replies "All the other men in town ride it over the hill, there's another town."
I heard that joke thirty years ago and it was a donkey in one version but the best version has him in the Saudi desert and a camel is the beast of burden.
