Classic Sesame Street - The Two-Headed Monster and the Word CLOSED

After their checkup, the Two-Headed Monster wears a baseball glove, but doesn't have a ball, so they go to Hooper's to buy one. When they reach the door, they're sad to see the closed sign, but David lets them in and eventually realizes they need a ball. As the monster turns to leave, they become sad again as the closed sign now faces inward.
