Tim (Bill Bixby) mentions that he attended "Cahuenga High" where he "served" under Miss Pringle -- which was actually an in-joke reference to Desilu Production's studios on Cahuenga Boulevard in Los Angeles, where such series as "The Andy Griffith Show" and "The Dick Van Dyke Show" were being filmed at this time. "My Favorite Martian" actually filmed its first 7 episodes at the Cahuenga facilities, too, although it thereafter moved to a different Desilu lot. Bill Bixby actually mentions his real high school (Lowell High School, which is in San Francisco) in the Season 2 episode, "Gone But Not Forgotten."
