- Awesome Music:
- Ensemble Dark Horse: Pepe the Prawn, who appeared in over half the episodes and has wound up playing a major role in most major Muppet works released afterward.
- Growing the Beard: Ironically, the final episode is when Steve Whitmire figured this happened, since it focused on one of the characters' personal lives outside of the studio. This would later become the premise for the 2015 series.
- Just Here for Godzilla: Despite a divided stance on the show's quality, the episodes hosted by Garth Brooks and Prince (back when he changed his name to the unpronounceable symbol) are considered very good, the Prince one even moreso following his death.
- Harsher in Hindsight: Or Hilarious in Hindsight depending on how you look at it. Everyone being upset over Garth Brooks trying to break away from country music mirrors people's reaction when he released a rock album under the persona, Chris Gaines.
- Hilarious in Hindsight: In the 203rd Episode: rKermit (in his Godzilla-like outfit) notes that he never good at playing a bad guy (Godzilla). 4 years later, a truly evil incarnation of Godzilla is made in 2001.
- Memetic Mutation: "Nice job, Kermit!" "Thank you!"Explanation
- Moral Event Horizon: Although his normal sketches dont cross it at all, Big Mean Carl crosses it on every Swift Wits segment where he eats an innocent animal as punishment for the contestant failing (even if it is the contestants fault.) Special mention goes to the sketch on the Pierce Brosnan episode where, even though the contestant got the answer right, he still eats the animal and then eats the contestant just to spite the host.
- No Yay: Johnny Fiama assures the audience this as he watches Bunsen try various outfits.Johnny: (singing) Pretty Bunsen, not that I'm into that, Pretty Bunsen.
- Replacement Scrappy: A major criticism of the series was that it largely sidelined the classic cast for new characters, most of whom were rarely, if ever, seen again after the show ended. Easily the biggest victim of this was Clifford, who replaced the iconic Kermit the Frog as the host.
- The Scrappy:
- Andy and Randy. Fans were just as irritated by them as the other characters.
- You'd also be hard-pressed to find anyone who likes Mr. Poodlepants. Reasons for disliking him usually have something to do with his ugly design.
- Signature Scene: Kermit's Stop Making Sense-esque performance of Talking Heads' "Once in a Lifetime" seems to be the most likely candidate.
- We're Still Relevant, Dammit!: Though not so much a case of "We're still relevant to the times, dammit!" as much a case of "We're still relevant without Jim Henson, dammit!". YMMV on how well the series answered that question.
