The 1970s-80s sitcom “Happy Days” – which was set in the mid-1950s to mid-1960s – had at least two strange and unlikely brushes with science fiction.

Mork (Robin Williams) was an extraterrestrial from the planet Ork who visited the Cunninghams. The sitcom “Mork & Mindy” spun off from this episode. 

And the 1980-82 Saturday morning cartoon “The Fonz and the Happy Days Gang” featured several members of the Happy Days principle cast along with an anthropomorphic dog named Mr. Cool joining a young woman from the future named “Cupcake” in her less than reliable time machine.
