The Muppet Show
In 1977, Don Knotts made a now famous appearance on “The Muppet Show”! Knotts played himself and was part of the majority of the show sketches.
The most popular scene was when Fozzie has a hard time coming onstage to talk to Don Knotts because he’s wearing sunglasses that are so dark that he can’t see anything or where he is going. The sketch ends with Don falling off stage!
