The Geefle and the Gonk

From Muppet Wiki

The Geefle and the Gonk is a story about two aliens on the planet Snew. The story is narrated by Jerry Nelson.

The aliens want to get some nectarines from a nectarine tree, as nectarines are the only food on Snew. Unfortunately, the Gonk is too short to reach the nectarines, and while the Geefle can reach them, he can't bend his arms, so he can't bring them to his mouth. They decide to work together to get the nectarines: The Geefle picks some for the Gonk, and the Gonk feeds some to the Geefle.

The Gonk suggests they call this process "Cooperation"; the Geefle wants to call it "Shirley".
