A group of Whatnots with rapidly growing hair sing "Aquarius" as the opening number in episode 316 of The Muppet Show. Written for the successful musical Hair, the song was further popularized by The Fifth Dimension who had a #1 hit record in 1969 with "Aquarius/Let the Sunshine In".

Sesame Street also did a parody of the song: "Telly's Aquarium."
