Andy Kaufman's appearances on Fridays (ABC's short-lived, but fondly-remembered attempt at their own SNL) were unforgettable - usually because he staged some elaborate mischief whenever he was booked.
Today's clip is from Andy's first appearance on Fridays after his staged fight with Michael Richards and announcer Jack Burns. He's born-again now, and happily engaged to Lawrence Welk show gospel singer Kathie Sullivan. (I sure hope she was in on the joke).
And here's Andy later in the show, preventing The Pretenders from performing. If you watch carefully, you'll see a young Larry David doing his "This way, Mister Doody" bit.
