“This series presents information based in part on theory and conjecture. The producer’s purpose is to suggest some possible explanations, but not necessarily the only ones, to the mysteries we will examine.“ 

So went the disclaimer before Leonard Nimoy went "In Search Of…” Amelia Earhart or Bigfoot or The Loch Ness Monster back in 1977-82.

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.
