A 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.
"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 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, "I'm sorry if I embarrassed you. You see, I'm a journalist and I've got an assignment to study how people respond to embarrassing situations." To which he responds, at the top of his lungs, "What do you mean $300?"
