One of the fun things about watching sitcom TV is when they stick in fun jokes from other fan genres.  Vectoring sci-fi elements have been a long-standing was to add interesting elements to a long-running show.

In the 1950’s, comedian Jack Benny turned over an entire episode of his comedy show to Rod Serling, where Rod tried to convince Benny that his entire show was a figment of his Twilight Zone imagination.

In the 1960’s, the Dick Van Dyke show did a Twilight Zone-oriented show, when Danny Thomas posed as an alien from the Twylo Zone, bent on replacing all of Rob Petrie’s work staff and loved ones with alien replacements.   This episode had a fantastic scene where a possessed Mary Tyler Moore emerged from a closet packed to the roof with walnuts…
