The Muppet Show. Rowlf and Fozzie - I Got Rhythm (s4 ep20)

"I Got Rhythm," from George and Ira Gershwin's Broadway musical Girl Crazy, was performed by Fozzie Bear and Rowlf the Dog in episode 420 of The Muppet Show.
Unfortunately, Fozzie is unable to sing the song in rhythm, despite guidance from Rowlf. In the end, Rowlf changes the song to "I Don't Got Rhythm," which works much better for Fozzie. Who could ask for anything more? Statler and Waldorf, who ask for earplugs.
