A man 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 man, who was deeply embarrassed and moved to another table.After a couple of minutes, the girl walked quietly to the man’s table and said with a laugh, “I study psychology, and I know what a man is thinking. I bet you felt embarrassed, right?” The man responded in a loud voice, “$500 FOR ONE NIGHT? …. I`M NOT PAYING YOU THAT MUCH!” All the people in the library looked at the girl in shock. The man whispered to her: “I study law, and I know how to screw people.”
