The Rambling Ghost appeared in "The Ghost That Sacked the Quarterback", an episode of The Scooby-Doo Show. He was the disguise of Buck Bender.
Buck Bender was an old coach that Mr. Prentice fired years ago. That newspaper clipping had incriminating evidence against Bender. He was taking revenge on the stadium owner for firing him.
In Scooby-Doo 2: Monsters Unleashed, the Rambling Ghost costume was on display at the Coolsonian Criminology Museum. The costume was to the left of Shaggy Rogers and Daphne Blake as they talked about putting up a good image.
