A guy is looking for a place to sit in a crowded library.
 
He asked a girl in the university library: "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 students in the library started staring at the guy; he was truly 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: "$1500 FOR ONE NIGHT? . . . THAT'S ROBBERY!"
   
All the people in the library looked at the girl in shock.
   
The guy then whispered: "I study law: I know how to screw people."
