A guys goes in a bar and orders for a beer. After a while this really gorgeous woman walks in and sits beside him. He starts thinking about talking her into bed with him and kindly turns to her, " Hi. Would you like me to buy you a drink?"
The woman turns to him and screams to the top of her lungs: "WHAT? YOU WANT TO FUCK ME? NO WAY!"
Every discussion in the bar suddenly stops and all the people are staring at the guy as the woman was leaving. The guy gets really embarrassed and stands still on his stool as if nothing had happened. After a while the same woman walks in, approaches him and tells him, "I'm sorry about that little incident but you see I'm a psychology graduate and I wanted to see how people react to embarrassing situations."
The guy then yells: "WHAT? TWO HUNDRED BUCKS FOR A BLOWJOB?"
