"Lydia, The Tattooed Lady" was one of Jim Henson's favorite songs. It was even performed at his memorial service in 1990 by Kevin Clash in the voice of Elmo. The tattoos drawn on Lydia were drawn on by Henson himself. Unlike other Muppet pigs, Lydia has hooves instead of hands. The punch at the end of the number was the first time Miss Piggy hit Kermit. This punch would later evolve into a karate chop.

Connie Stevens was the second and last guest star to receive a Muppet Likeness of herself at the end of the show.
