A man asks to go to the toughest prostitute in town, so he is given the address. He goes and knocks on the door and the prostitute lets him in and says,"grab yourself a bottle of beer while I undress." When he turns around he sees her naked on her elbows and knees on the floor. The man says,"oh, you want to start way?" The prostitute says,"No, I thought you were going to open your beer!"
