Out on the town one night, a young lad successfully chats up an attractive female, and they go back to her place. "You can't make any noise," she warns him. "My parents are upstairs and if they find out they'll kill us!" Things start getting heated on the sofa, but after a while alcohol gets the better of the man's bladder. "I have to go," he says. "Well you can't go upstairs, it's right next to my parents' bedroom," she replies. "Use the kitchen sink". So he dutifully retires to the kitchen. A few minutes later, he pops his head round the door and asks, "Do you have any paper?"
