This thread reminds me of a joke.

A girl meets a guy in a night club and takes him back to her home where she lives with her parents. She explains they can't go upstairs as her parents will wake up so they snuggle down for some action on the settee in the lounge.

Just as they undress, he announces he needs the toilet and is getting desperate so she again explains he can't go upstairs where the only toilet is, due to her parents waking. She thinks for a second and then tells him to use the kitchen sink instead.

So of he goes and is gone for about 5 minutes. The girl, now getting a bit worried was just about to go and investigate when his rather sheepish head pops round the door of the lounge and he says;

"Hello love, where do I find the loo paper"
