The final scene of “Newhart” will always remain a classic TV moment - brilliant!

That scene is without peer the best and funniest TV scene ever. As I recall, the idea was hatched by Susanne Pleschette and Bob Newhart’s wife. They filmed three endings with only the actors and the director in the studio.
Newhart has always been a favorite.
