An old man goes to the barbers for a shave, he tells the barber he wont be able to get every whisker due to the wrinkles in his skin, so the barber gives the old man a small wooden ball to put in his mouth stretching his skin, he then proceeds to give the old man the best shave of his life, "that's great" says the old man "but what would of happened if I had swallowed the ball". "you just bring it back in a few days like everyone else does".
