One day a lion was walking around the jungle sad and lonely, when he spotted a monkey up in a tree. He yelled up to the monkey to come down and play, but the monkey was too scared. So the lion asked the monkey what he could do to make him feel comfortable enough to come down. The monkey said, "If you tie yourself up I'll come down." So the lion ties himself up, but as the monkey came down he started shaking.
The lion said, "Hey, monkey, you don't have to be scared! I'm not going to eat you; I'm tied up real tight."
"I know," said the monkey. "That's not why I'm shaking."
"So why are you shaking?" asked the lion.
"Well," said the monkey, "it's just that I've never had sex with a lion before."
