Spanky is an intelligent gorilla trained at the Simionics Institute in The Middleman episode "Pilot Episode Sanction." Obsessed with gangster movies, Spanky sees himself as a mobster, murdering the local mafia and spouting dialogue cribbed from the likes of The Godfather and Scarface. He leaves banana peels near his victims. Eventually, the Middleman and Wendy Watson discover that the gorilla is in fact the pawn of Dr. Gibbs.

The gorilla puppet was recycled from George of the Jungle.
