Psychology

A very shy guy goes into a pub on Valentine's Day night and sees a
beautiful woman sitting alone at the bar. After an hour of gathering up
his courage he finally goes over to her and asks tentatively, "Um, would
you mind if I brought you a drink?" She responds by yelling, at the top
of her lungs, "No, I won't sleep with you tonight!"

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

After a few minutes, the woman walks over to him and apologises. She
smiles at him and says, "I'm really sorry if I embarrassed you just
then. You see, I'm a graduate student in psychology and I'm studying how
people respond to embarrassing situations."

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