A guy asked a girl in a library; "Do you mind if I sit next to you?"
The girl answers in a loud voice' "I DON'T WANT TO SPEND THE NIGHT WITH YOUUU!!"
All the students in the library start staring at the guy. He was very embarrassed. After a couple of minutes, the girl walks quietly to the guy's table and says "I study psychology and I know what a man is thinking... I guess you felt embarrassed right?"
The guy responses in a very loud voice; "$200 JUST FOR ONE NIGHT!!?? THAT'S WAY TOO MUCH!!"
.....and all the students in the library look at the girl in shock and the guy whispered in her ear; "I study Law and I know how to make someone look guilty!"
