A very shy guy goes into a pub on Valentine's Day night and sees a beautiful young 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 started staring at them. Naturally, the guy was terribly and completely embarrassed and he slinks back to his table totally red faced.
After a few minutes, the woman walks over to him and apologizes. 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."
At this the guy responds, at the top of his lungs, "What do you mean? $300?"
