One day, at the bar...

A very shy guy goes into a bar and sees a beautiful woman sitting by herself at the bar. After several minutes 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?"

To which she responds by yelling, at the top of her lungs, 

"NO, I WON’T GO TO BED WITH YOU!”

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, "I'm sorry if I embarrassed you. 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, $2,000?"
