The gang encounters Don Adams, who's working as an exterminator and has been hired to clear the bugs out of famous film star Lorne Chumley's supposedly haunted mansion.
This episode contains examples of:
- Expy: Otto the Butler is eerily similar to Max from Sunset Boulevard: as a bald, monocle-wearing German butler/director to a reclusive silent movie star hoping to make a comeback.
- Man of a Thousand Faces: Lorne Chumley is directly called this, tying in with his status as a parody of the trope namer, Lon Chaney.
- Mathematician's Answer: Don Adams tells Shaggy and Scooby that it must have been termites that slammed the door.Shaggy: What kind of termites slam doors?
Don Adams: Very rude ones. - No Celebrities Were Harmed: "Man of a Thousand Faces" Lorne Chumley is an obvious riff on 1920's film actor Lon Chaney, right down to the nickname.
- Not a Mask: In the climax, Don Adams keeps removing masks off Lorne Chumley until by accident he pulls at Chumley's face. "Well, I guess that really is Lorne Chumley".
- Screw This, I'm Outta Here: Don Adams' three regular assistants quit prior to his episode rather than go exterminate the supposedly haunted house.
