Humphrey Spoolman is a recurring character in the series. He is an elderly balding man with grey hair and 3 spots on the top of his head. He is short and walks with a cane. He wears glasses, and brown jacket over a yellow shirt with green pants.
He is called mister Spoolman by Burt at the start of Drive-In Me Crazy when he tries to swap a popcorn machine at the House Of Swap. Burt asks this means he is getting a new one for the Bootsville Drive-In.
In You Scream, I Scream he is feeding what looks to be popcorn (probably from his theatre) to 3 birds while sitting on a bench. He is knocked off the bench (and probably unconscious, indicated by his pupils changing to Xs) by a barrel which shatters upon hitting the back of his head. It is not clear whether or not he survived this injury.
