National Lampoon's Christmas Vacation (1989)

Revealing mistake: When Clark starts to set up his Christmas lights, there is a scene where the ladder collapses. If you look closely you can see the wire coming out from under his jacket to keep him from falling forward. (00:20:55)

Todd: Hey, Griswold. Where do you think you're gonna put a tree that big?
Clark: Bend over and I'll show you.
Todd: You've got a lot of nerve talking to me like that, Griswold.
Clark: I wasn't talking to you.

Trivia: When Clark smashes up the decorations when he can't get the lights working, Chevy Chase genuinely broke a finger when he punched Santa, but stayed in character, kicking the decorations instead, and that's the take used in the film.

Question: At the Christmas dinner, what is the tree ornament behind Clark as he's cutting the turkey?
