A beautiful woman is standing on a bridge, looking over the side and thinking about jumping off.
A homeless man walks up to her.
She sees the man coming and says, "Go away! There's nothing you can say to change my mind!"
He says, "Well, if you're going to kill yourself anyway, why don't we have sex? At least I'll enjoy it."
"Absolutely not! You're disgusting!", she replies.
The man turns and starts walking away.
"Is that all you're going to say? You're not going to try to convince me that life is worth living? Where are you going?"
"I have to make it down to the bottom. If I hurry, you'll still be warm!", he says.
