Dr. Teeth, Floyd and Gonzo sing "When You're Smiling" backstage as part of a medley intended to cheer up Fozzie during the UK Spot in episode 506 of The Muppet Show. The song is a swing standard, made famous by Louis Armstrong.

The song was previously performed by a sobbing Rowlf and Jimmy Dean on episode 126 of The Jimmy Dean Show. They reprised the song in episode 304, with the lyrics replacing "Smiling" with "Laughing."
