Trivia: Fred and Barney Meet the Thing
- Hey, It's That Voice!: Benjy Grimm was voiced by Wayne Norton, and the Thing was voiced by Joe Baker. Norton also voiced Pontoffel Pock, a Dr. Seuss character. Baker also voiced Larry Fine.
- In Brazilian dubbing, Benjy was voiced by Cleonir dos Santos, who, curiously, dubbed Human Torch in Hanna-Barbera's Fantastic Four cartoon. The Thing was voiced by Orlando Drummond, who dubbed the Thing also in the 1978 FF cartoon and is known for dubbing Scooby-Doo from the beginning until the first season of Scooby-Doo! Mystery Incorporated (he was replaced for the second season, along with most of the cast, except Fred).
