Psychology and the Law. A guy was looking for a place to sit in a crowded university library. He asked a girl *"Do you mind if I sit beside you ?"* The girl replied in a loud voice: *"NO I DON'T WANT TO SPEND THE NIGHT WITH YOU!"*... All the people in the library started staring at the guy, he was deeply embarrassed and moved to another table. After a couple of minutes, the girl walked quietly to the guy's table and said with a laugh: *"I study psychology, and I know what a man is thinking, I guess you felt embarrassed, right?"* The guy then responded in a loud voice: *"$500 FOR ONE NIGHT ? ... THAT'S TOO MUCH!"* All the people in the library looked at the girl in shock. The guy whispered to her: *"I study law, and I know how to screw people"*.
