Big Bird plays a rhyming guessing game with his puppet Gus, while Gordon engages Elmo in finding things that rhyme with household items, accidentally summoning a Rockhead who makes rock-themed puns. When Elmo brings his aunts to rhyme with "pants," the Rockhead learns more about his family. Later, Big Bird finds few people willing to listen to his nature poem until the Rockhead offers genuine attention. Sponsors: A, B, 8
