A very 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, "Um, would you mind if I chatted with you
for awhile?" 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 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 do you mean $200?"
