We all know that Guy Smiley is not around on Sesame Street anymore, because of Jim Henson's death, and I know what his final appearance is. It was him singing "Air" after he asks, "Did somebody say 'air'?!?'" whenever the barbar anything muppet says words that rhyme with air like hair and chair to the pink boy anything muppet. I have the last appearance of Guy Smiley on tape.
