Jack and Jill

From Muppet Wiki

Jack and Jill went up the hill, to fetch a pail of water, in a nursery rhyme. The characters have been included in various Muppet productions:

• Kermit the Frog reported live from the scene in a "Sesame Street News Flash" sketch. Jack needs someone to go up the hill with him. First he chooses Mervin, then Francine and Gladys the Cow. Finally Jack chooses Jill, who refuses go up the hill with him again, so he asks Kermit to fill in. (EKA: Episode 1071)
• Jack and Jill attend Storybook Community School on Sesame Street (in season 36 and 37) with other famous characters from children's literature and nursery rhymes.
• A 2007 Sesame Street book, Guess Who, Abby!, features Elmo and Zoe as the twosome.
• Jack and Jill also appear in the 2007 book Abby Cadabby's Rhyme Time, rhyming "tumble" with Jack's grumpy "grumble".
• The story of "Jack & Jill" was told in a segment of Mother Goose Stories.
