A man enters a barbershop for a shave. While the barber lathers him up, he mentions that because his cheeks are slightly hollow, he finds it difficult to get a close shave on his cheeks. "I have just the thing," the barber says, and from a drawer he produces a wooden ball about the size of a large grape "Just put this between your cheek and gum." The customer puts the ball in his mouth, and the barber proceeds to give him the smoothest shave the man has ever experienced. As the barber finishes, the man asks, "And what if I swallow it by accident?" "That's no problem," says the barber. "Just bring it back tomorrow, like everyone else does."
