A student is looking for a place to sit in a crowded university library.

He asked a girl sitting by a table alone: - "Do you mind if I sit beside you?

The girl replied with 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 with a loud voice: - "$500 FOR ONE NIGHT? . . . THAT 'S WAY TOO MUCH!"

All the people in the library looked at the girl in shock. The guy whispered in her ear:

"I study law, and I know how to screw people!"
