Role in episode
He is very cruel to SpongeBob and Patrick, even though they are not supposed to be at the prison. He acts like a military sergeant/prison guard, and is tough. He is very harsh to the criminals and hates almost everything except the play that SpongeBob arranges.
R. Lee Ermey, the portrayer of the Warden, did in fact used to be in the military, just like this character.
The Warden is voiced by the late Ronald Lee Ermey, the same actor who played Gunnery Sergeant Hartman in the classic Stanley Kubrick film Full Metal Jacket (Ermey's portrait of Hartman has been parodied in popular culture).
The warden is similar to the warden in the novel and its movie adaptation Holes.
Being the stereotype drill sergeant, he yells his words and rarely speaks in a normal tone.
