The concurrent sexual lives of best friends Jonathan and Sandy (Jack Nicholson and Art Garfunkle) are presented, those lives which are affected by the sexual mores of the time and their own temperament, especially in relation to the respective women who end up in their lives.

Two identical twin sisters, separated at birth by their parents’ divorce, are reunited years later at a summer camp, where they scheme to bring their parents back together.

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.”
