Ben is having a drink in his local bar when in walks this gorgeous woman. Ben, not being too shy, goes up and sits next to her. He buys her a drink and then another and then another. After this and the accompanying small-talk, Ben asks her back to his place for a "good time."
"Look," says the woman, "what do you think I am? I don't turn into a slut after 3 drinks, you know!"
"OK," replies Ben, "so how many does it take?"
