17x93 - Sesame Street

At dusk, Oscar shows Luis and the kids a demonstration of how the Earth revolves around the sun, using a large apple as the Earth (with Slimey inside) and a flashlight as the sun, which Luis operates. Bob encounters Oscar arguing with Telly about whether nighttime is a happy time or a sad time. Oscar gives his reasons why it’s a happy time, and Telly gives his reasons why it’s. Sponsors: D, G, 8
