Count Floyd's Scary Stories: Floyd tells the story of "The Attack of the Spooky Chiller 50-ft Potato Monsterman." Also, he interviews a couple of kids who think they're Vanna White and Ed Grimley, respectively.
This episode is based on a segment from the 1985 Showtime Special "Concert For the North Americas," specifically a sketch called the Full Moon Sketch. In this sketch Ed Grimley's cousin Mr Talbot behaves strangely on the full moon, and may or may not be a werewolf.
Mr. Talbot is named for Lawrence Talbot, the main character in the definitive werewolf movie, 1941's The Wolf Man, starring Lon Chaney, Jr.
