the first seven minutes make up my favorite scene in any television comedy; note how generously Griffith gives focus away to the transcendent Don Knotts but still gets the best moment with a single instance of disbelieving silence; I once stopped and watched this scene in its entirety on the floor of the San Diego Comic Con; there were about six of us, transfixed; after it was over, we smiled and looked at each other and then went back to our days; RIP
