knocking the meatball off the christmas tree

I don't care how bad your Christmas is going. It doesn't matter if the family tree caught fire and burned every present under the tree, including that fireproof safe your aunt sent you at the last minute. Jay Thomas will save it for you.

Every year at Christmas time except in 2007 because of the Writer's Guild Strike, the actor and comedian goes to David Letterman's Late Show to help Dave knock the meatball off the Christmas tree and tell the greatest showbiz story I've ever heard in my life. If you don't want to spoil the story for you and your family when he returns to the Late Show on Wednesday, go ahead and watch it anyway. It will STILL be just as funny. I've heard it a thousand times and Thomas' style and delivery just makes it funnier.
