Linda Lavin and the Muppets sing "For He's a Jolly Good Fellow" to Kermit in honor of his birthday at the end of episode 406 of The Muppet Show. After the song, Kermit admits that his birthday isn't for four months.
The British/Australian version of the song, which replaces the lyrics "which nobody can deny" with "and so say all of us," is sung twice in "Kermit's Story," the first issue of The Muppet Show Comic Book. The Muppets first perform the song to cheer Kermit up, but this attempt, which ends with Miss Piggy emerging from a cake dressed as a lily pad, ultimately fails. Once Robin has figured out how to ease his uncle's troubled spirit, though, Kermit insists that his nephew is honored with a verse of the song.
The popular children's song "The Bear Went Over the Mountain" is often sung to the same tune as "For He's a Jolly Good Fellow."
