A guy is 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:
"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:

"$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 make people pay
For their stupidity."
