Scooter talks Fozzie into doing "the telephone pole bit," and Fozzie practices dutifully until he finds out what the bit is: Fozzie dresses up as a public telephone, and Scooter asks what his name is. "Mike Oznowiczki," Fozzie says, and Scooter exclaims, "Oh, so you're the telephone Pole!"

The Muppet Theatre is plagued by a variety of pig-related problems, both onstage and off. First, The Bouncing Borsalino Brothers flub their act and crash through the stage floor. Backstage, Miss Piggy throws herself at an uninterested Kermit and then jealously interrupts his onstage Talk Spot, physically threatening guest star Florence Henderson, whom she thinks is horning in on her frog. The feud continues in the Panel Discussion as Florence throws pig slurs around.

Kermit is skeptical when everyone backstage is terrorized by "the Phantom of the Muppet Show." There turns out to be one, though -- Uncle Deadly, a monster-actor who performed in the theater years ago. After being panned by the critics, he vowed never to perform there again, and not to let anyone else perform either. He warns the Muppets, "Leave or be doomed!"

Tired of the "embarrassingly square" theme song, bass player Floyd Pepper informs Kermit that he and the rest of the orchestra pit (except Rowlf) are quitting. Kermit says their conductor Nigel will write a new theme, but Floyd refuses: "He wrote the first one, man." Floyd performs his idea for a new theme, a dreadful Zappa-esque piece called "Fugue for Frog." Kermit won't use it and refuses that Floyd submits to Kaye Ballard a petition about the theme song, so the band leaves. The closing theme is performed solo by Rowlf on the piano.
