When the series title appears, Gonzo does a different gag with each episode.
At the end of the closing credits, Zoot blows his horn and the Henson International Television logo pops out of it onto the screen.
At the end of the closing credits, there is a scene with Statler and Waldorf.
With the exception of the title; there are no opening credits.
Occasionally, the end theme would be performed in a different way.
- Kaye Ballard show: All the band members, except Rowlf, quit the show. Rowlf is left to play a piano-only version of the theme tune.
- Loretta Lynn: Both the opening and closing credits in this show are done differently. The show is performed at the local railway station and the lyrics to the opening theme are appropriately changed - Cast: It's time to get things started, on the most sensational, inspirational... Fozzie: This week's sort of, railroad stational. The band play an off-key version of the end theme. Rowlf explains the reason to the audience - "No wonder this sounds bad. We're playing a timetable!"
- Harry Belafonte: The cast sing the song "Turn the World Around" while the end credits roll.
- Spike Milligan: The cast sing the song "It's a Small World" while the end credits roll. Guest Spike Milligan tells them to keep quiet as he's trying to sleep. At the same time, the end theme is played down and Kermit, who is still on stage, yells out that the music be stopped.
- Roger Miller: The whole cast, except Gonzo, have turned into chickens. As a result, all the band play the end theme as chickens. Animal pecks at his drums, while Rowlf and another chicken play the piano.
- Dudley Moore: Dudley's Music Machine plays a bizarre rendition of the end theme. It sounds off-key and is done in various styles including jazz, stripper music, chase music.
- Mac Davis: This is the episode where Beaker gets duplicated by Dr. Bunsen Honeydew's duplicator machine. The Beakers play the end theme.
