Shy guy goes into a bar

A very shy guy goes into a bar and sees a beautiful woman sitting at thebar. After an hour of gathering up his courage he finally goes over to her and asks, tentatively, "Um, would you mind if I chatted with you for awhile?" 
She responds by yelling, at the top of her lungs, "No, I won't sleep withyou tonight!" Everyone in the bar is now staring at them. 


Naturally, the guy is hopelessly and completely embarrassed and he slinksback to his table. 


After a few minutes, the woman walks over to him and apologizes. Shesmiles at him and says, "I'm sorry if I embarrassed you. You see, I'm agraduate student in psychology and I'm studying how people respond toembarrassing situations." 


To which he responds, at the top of his lungs, "What do you mean \$200?"
