Knock Knock... Who's Ed / One + One = Ed

S2 E2: "Knock Knock...Who's Ed" Sarah locks the Eds out the house just as a Cyclops Movie Marathon is about to start. The Eds try to get back inside the house. When that fails, they try to get into the other kids' houses to watch their show. "One + One = Ed" Edd tells Eddy and Ed that if you want to understand something, you have to take it apart. Ed, Edd, and Eddy start taking apart everything in the cul-de-sac. Before too long, even reality isn't safe.
