Joe is having a drink in his local bar when in walks this
gorgeous woman. Joe,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,Joe 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 Joe, "how many does it take?"
