I personally think that the show got better per season, so if asked the question. Seasons 2-5. Season one seemed sort of tame to me, plus I don't like Hilda. I thought she was kind of mean to Fozzie and Gonzo which both didn't have much self confidence at the time. Still there was some great sketches in season 1 like "Sonny", "Feaver with Rita Moando", Classics like "In a Little Spanish Town", "Java", "You do something to me", "Hugga Wugga Buggy Mugger", etc. Though I think the last two seasons were more wilder, esspecially having Chris Langum on the team. It became more British humor like which I love in it's self. Especially Gerri and the Actrics. lol Still cracks me up to this day lol And just now I realized "geriatrics" "Gerry and the Actrics" lol the play on words. It's funny, I never usually get these jokes until later in my life. lol Some days I just think of something and out of the blue I'm like "OH I GET IT NOW!" lol
Also even though a special and not an episode, The Muppets Go To The Movies to me was like the big finally of The Muppet Show. It had it's trademark humor and just craziness.
Waldorf: Let's give them three big cheers
(chairs are thrown at them)
Statler and Waldorf: That's Cheers! Not Chairs! lol
I really miss The Muppets doing this kind of humor. lol
I forgot to mention, Trudge Trudge. lol Classic piece of weirdness. This I also miss about The Muppets.
