An Inside Job (1987) ****

A truly disgusting, truly brilliant and truly hilarious cartoon set in the mouth of a dentist's patient, who is robbed of his gold teeths by a clever sadist, who plants tiny explosives and retrieves the loot. Bizarre vocal impersonations (including Jack Nicholson's, who made his film debut in "The Little Shop Of Horrors" playing a masochistic patient who adores his visits to the dentist). A brilliant little film, but guaranteed to shock and disgust many viewers.
