Guy picks up a girl at the nightclub. She invites him back to her place but warns him that they’d have to be really quiet because Mum and Dad would be sleeping in the next room.

They sneak up to her room and start to get undressed. Before they get completely naked though, the bloke announces that he needs the toilet.

“You can’t use the toilet up here,” said the girl, “The flush will wake my parents. You'll have to go downstairs and use the kitchen sink.”

So he sneaks downstairs and comes back 5 minutes later, “Have you got any toilet paper?”
