At the start of the opening credits, an announcer says: "Welcome to The Happy Days 2nd Anniversary Special." There are no standard closing credits. People dance in the background, and the gang is at a booth at Arnold's as the credits are rolled to, first, an instrumental version of "I'm Walkin'" followed by the regular closing theme.
