Jim Henson and his Muppets were part of the first season of 'Saturday Night Live' because NBC was hoping to tamp down Lorne Michaels' countercultural plans for the show.

'The Muppet Show' debuted in the UK because it was rejected by every US network.

Before 'The Muppet Show,' Jim Henson produced slapstick coffee commercials featuring the puppets.

Before 'SNL,' producer Lorne Michaels was a performer

Michaels was a costar on "The Hart and Lorne Terrific Hour," a popular show on the Canadian network CBC. As these clips show, it was a standard variety show, something Michaels would intentionally react against with "SNL."

“SNL” producers aimed to cast relative newcomers for the show’s first season, convinced that amateurs would infuse the show with the countercultural spirit Lorne Michaels envisioned.

Lorne Michaels left the show in 1980, citing burnout and disagreements with network executives. He tried several gigs, including a sketch comedy show called “The New Show” that was strikingly similar to “SNL,” but nothing stuck. He returned to "SNL" in 1985.

Jim Henson and his creative team constructed several optical illusions to make the Muppets appear as though they walked through the real world.

'SNL' was originally called 'NBC's Saturday Night'

Another show already owned the title: the short-lived "Saturday Night Live with Howard Cosell."

O'Hara was only a cast member for a week and never appeared on-air during that time, though she eventually hosted 'SNL' twice, in 1991 and 1992.
