Get Even

A very shy guy goes into a bar and sees a beautiful woman sitting at the bar.
After an hour of gathering up his courage, he finally goes over to her and asks tentatively.

"Umm, would you mind if I chatted with you for awhile?"

She yells at the top of her lungs,
"No, I won't 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 apologises.

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."

At the top of his lungs, he responds,

"What do you mean '200?"
