A man goes to the barber shop for a shave. While the barber is lathering him up, he mentions the difficulty he has been having getting a close shave around the cheeks.
"I have just the thing," says the barber, taking a small wooden ball from a nearby drawer, "Just place this between your cheek and gum."
The man places the ball in his mouth and the barber proceeds to give him the closest shave he has ever experienced. As the barber is finishing up, the man asks awkwardly, "But what if I swallow it?"
"No problem," says the barber. "Just bring it back tomorrow like everyone else does."
