She yells "No, I won't sleep with you tonight, you pig!" Everyone in the bar stops and stares. Completely embarrassed, the guy slinks back to his table with a red face. After a few minutes, the woman walks over to him and apologises. She smiles and says "I'm sorry if I embarrassed you. I'm a graduate student in psychology, and I'm studying how people respond to embarrassing public situations". To which the guy responds as loudly as possible "WHAT DO YOU MEAN $200 FOR A BJ?"
