Two hunred dollars

A guy is sitting in a bar, absolutely drooling at a beautiful young thing in her short, pink mini-dress. Using a time-honored icebreaker, he sends her a drink.

"How lucky am I?" he thinks as she comes over and sits down beside him.

The woman says softly, "Look, you seem like a nice enough guy, so here's the deal: I'm a working girl. We can skip the small talk; just pay me two hundred dollars."

He replies, "I've got no problem with that but, since we're being straightforward I must tell you this: when I come, I go nuts; I bite, I scratch, I kick, punch, pull hair, break furniture, and just plain destroy the place."

"Oh, really? And how long does that last?" she asked sweetly.

"Usually until I get my two hundred dollars back!"
