A guy goes into a bar and sees a beautiful woman. After an hour of gathering up his courage he finally goes over to her and asks, tentatively, Um, would you mind if I chatted with you for a while?

She yells, No, I wont sleep with you tonight!

Everyone in the bar is now staring at them. Naturally, the guy is hopelessly and completely embarrassed and he slinks back to his table.

After a few minutes, the woman walks over to him and apologizes. She smiles at him and says, Im sorry if I embarrassed you. You see, Im a graduate student in psychology and Im studying how people respond to embarrassing situations.

To which he responds, at the top of his lungs, What do you mean $200!?!
