The Indecent Dentist - From Playboy's Totally Busted, a new assistant witnesses the dentist giving a hot chick some gas who then begins to get stimulated. Her bra is quickly undone and the dentist leaves the room to get his camera as the assistant carries on fondling the chick's breasts until she snaps out of it. The dentist wanders back in, acting surprised and placing the blame on his assistant.
