The Geefle

The Geefle is an alien who appeared in the Sesame Street story of "The Geefle and the Gonk". The Geefle can't bend his elbows, so he can't feed himself nectarines. The Gonk also has trouble; he's too short to reach the nectarines. The two aliens learn to cooperate: the Geefle picks nectarines for the Gonk to eat, and the Gonk feeds some of the nectarines to the Geefle. According to the story, he is the co-creator of cooperation. He recommends naming the method Shirley.
