The Muppet Show (1976) - 10 mistakes in entire show

Audio problem: In the ballroom sketch when Janice is talking to Zoot, her mouth starts moving before we hear her even say anything.

Visible crew/equipment: Several times during "Love Ya To Death", you can see Jim Henson's head popping up from under Dr. Teeth.

Visible crew/equipment: During "Veterinarian's Hospital" when Dr. Rowlf says, "Day in and day out, it's the same 'ol routine!" you can see a puppeteer's head behind him.

Visible crew/equipment: When the group of pigs, chickens and frogs are singing "Temptation," the head of Dave Goolez (the guy who does Gonzo) is visible under the second chicken on the right several times during the sketch.

Visible crew/equipment: When Zero Mostel is dispelling the monsters, you can see a puppeteer's head to his right for a brief moment before it disappears.

Visible crew/equipment: As Animal hits the cymbals, the top of a puppeteer's head pops up for a split second next to the drum.

Visible crew/equipment: While Link Hogthrob is singing, "I Talk to the Trees", you can see a puppeteer's head briefly during the song.

Visible crew/equipment: Right after J.P. Gross says, "What for? No money in hog calling!", you can see a puppeteer's head to his left.

Revealing: When Luke Skywalker is introducing his 'cousin' Mark Hamill at the end, you can tell it's a split screen by the fact that Luke looks right past him, even once he's on stage.

Continuity: When Diana Ross finishes her first song, the bird has both his feet on the ground; in the next shot, the bird has one leg raised, without enough time passing to do so.
