"Scratch My Back" is a Sesame Street song sung by Bip Bippadotta and two monsters named Jack and Jill. The song describes about the monsters' relationship with each other and how they swear that they will always be there to scratch each other's backs. By the end of the song, Bip ends up scratching both their backs unbeknownst to the monsters. Jack is performed by Kevin Clash, and Jill is voiced by Ivy Austin. Richard Hunt was originally going to perform the Jill puppet, but let David Rudman take over (on his first day performing on Sesame Street).
