Baby Bobby from Bingumton was a contestant on the Sesame Street game show, "To Tell a Face". In that game show, he must identify the face of his grandmother. After taking a close look at each of the three grandmothers (including a Pumpkin Anything Muppet man, a Large Lavender Live Hand Anything Muppet elderly woman, and a dog), Baby Bobby assumes that his real grandmother is "ga-ga-goo" (that's baby talk for grandmother #2).
