The show uses (and reuses) many audio clips taken from old cartoons, movies, and TV shows. Among the most commonly heard are two soundbites from classic Bugs Bunny cartoons, which have come to play before the credits at the end of each episode. Bugs's line, "So long, Screwy! See you in St. Louie!" is taken from Hare Trigger (1945), and the "We're the boys of the chorus; we hope you like our show..." ditty is taken from What's Up Doc? (1950).
In 2022, Rich Koz - "Svengoolie" was awarded Favorite Horror Host of 2021 in the 20th Annual Rondo Hatton Classic Horror Awards.
The "Three Stooges" footage that is briefly shown in the intro sequence comes from Sing a Song of Six Pants (1947). NOTE: This movie connection cannot be made at series level.
Though he plays the ghoulish horror host Svengoolie, Rich Koz is actually credited on-screen as "Man in Hat." Likewise, musical director Doug Scharf's character is known as Doug Graves, but he is credited on-screen as "Man in Other Hat."
Occasionally mentioned Berwyn, Illinois when reading fan mail or at other times during the breaks with the host, Svengoolie (before going to commercial, etc.). Doing the name of the Chicago suburb was a running joke for the show.
