"Any Old Iron" was the UK Spot for episode 214 of The Muppet Show. It is sung by Kermit the Frog, who is then joined by Fozzie Bear, two Whatnots, and the audience. One of the Whatnots is missing a pupil throughout the number. Louise Gold performed that Whatnot and noted in an interview that this was the last sketch filmed for the episode, and there was only time for one take.
