The Hilarious House of Frightenstein was a Canadian children's television series which was produced by Hamilton, Ontario's independent station CHCH in 1971. It was syndicated to television stations across Canada and the United States and occasionally still appears today in some TV markets. In Canada, the series is currently airing on SPACE, Drive-In Classics and Razer.

A quirky sketch comedy series, the show's cast included Billy Van, Fishka Rais, Guy Big, Mitch Markowitz, Vincent Price and Julius Sumner Miller. Van, in fact, played the vast majority of the characters.

All 130 episodes of the series were made in one single nine-month span of time starting in 1971, and the scenes with Price and Miller were all filmed within one summer.

Although most of the show was played for laughs, the regular science segments featured a genuine professor who studied under Albert Einstein and who had also been resident scientist on the original "Mickey Mouse Club".

At the end of the credits for every episode, a different character would say, "The show is definitely over."
