A man stops into this little backwoods restaurant for lunch, and after finishing his meal he inquires the way to the rest room.

He was told that it's around the back of the building he heads through the back door, finds the outhouse and takes a shit, only to discover there's no toilet paper. But there is a sign on the wall that reads, 'Wipe yourself with your finger, then insert the finger into this hole, and your finger will be cleaned with great attention'

So the man wipes up and sticks his finger through the hole. On the other side is standing a little boy holding a brick in either hand, who claps them together at the sight of the finger poking through.
