I was the only guy I knew who liked the "edgy" Muppet monster sketches on Saturday Night Life in late 1975 and early 1976, and thought they were hilarious. The SNL writers hated them, and eventually they got dropped from the show. But that was one of the first attempts by Jim Henson to prove the Muppets could be hip and funny and have sort-of adult comedy without crossing any lines. The Muppet Show didn't happen for more six months after that, but he finally got the success he was looking for... and the show led to the films, and eventually a vast empire (which the family sold to Disney). Jim Henson Productions no longer owns the original characters or the word "Muppets," so they're doing some different things these days... but they are still using puppets and doing some kind of edgy plays and performances in LA.
