Shemp has been ill with a toothache. The Stooges’ friend Claude (Matt McHugh), a self-proclaimed doctor, gives Moe and Larry some specific instructions on how to cure the toothache, which, of course, they misinterpret every which way possible. After finally yanking the troublesome tooth, Claude suggests they take Shemp on a camping trip for a little R&R. Since the Stooges do not own a car, Claude offers to sell them a car that turns out to be a “lemon.”
