A young bloke is having a drink in a bar when he notices an attractive young lady sitting by herself. He politely goes over and asks if he might buy her a drink. To his surprise and embarrassment, she says at the top of her voice "What! Would I sleep with you? What type of girl do you think I am?"

He slinks back to finish his drink, when the girl comes over to him and says "I'm sorry if I upset you. I'm a psychology student, and I'm studying how people react to sudden awkward situations. I'd love to have a drink with you."

The poor guy turns to her and says, so everyone in the bar can hear "What! $200!"
