National Lampoon's Christmas Vacation (1989)

Factual error: In the scene where Clark is working on the lights the full moon is shown. This is December 14th according to the advent calendar. On December 24th when Santa's sleigh goes sailing over the moon, it is still full.

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?
