Mr. Good Clean Fun is a traveling school assembly performer, who specializes in good personal hygiene and (more recently) getting kids to do their tests. He was employed by the Edu-Fun corporation, also the maker of Funtime. Recently, he was excommunicated by McQuarrie Middle School due to lack of demand and was seen working as a busboy at Derwin's BBQ #2. But after the fall of Funtime, he was hired as the chorus teacher of MMS and was an extremely ineffectual chaperone in Emperor Pickletine.
Mr. Good Clean Fun's inspiration from real life is an actor and former elementary school librarian named Brian Compton.
