French joke:
Little guy wants to join the Foreign Legion. Commandant tells him he's way too small. Little guy replies that he's tough, all heart--just set him a challenge and he'll do it.
OK, says commandant, you have three tasks:
--You got to smash this huge boulder into gravel with a hand hammer;
--You got to break the arm of a gorilla we got in a cage here;
--You got to get buggered by a sailor we're keeping in the brig.
OK, says the little guy, I accept.

He goes out back and takes his little hammer to the huge boulder, and, within three hours, it's just a pile of gravel. Then he goes into the gorilla cage. There's about twenty minutes of howling and screaming. Then the little guy emerges, bloody and disheveled, and says, "OK, where's this sailor whose arm I'm supposed to break?"
