Parents Upstairs

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 toilet paper?
