A shy guy walks into a bar and sees a beautiful blonde woman sitting at the counter. After an hour of gathering up his courage he finally goes over to her and asks, tentatively,
"Um, do you mind if i buy you a drink?"
She responds by yelling, at the top of her lungs,
"No, I won't sleep with you tonight!" And walk out the door. Everyone in the bar is now staring at the guy.
Naturally, the guy is hopelessly and completely embarrassed and walks aways to his table.
After a few minutes, the blonde woman returns and 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?! $200 FOR A BLOWJOB?!"
