Visible crew/equipment: After Mortimer's comment that Billy Ray has probably been stealing since he could crawl, when it cuts to the two officers opening the squad doors to place Billy Ray at the back of the vehicle, the barndoor set lighting is visible over the squad car at the top right corner of the screen.

Other mistake: In the end credits, Santa's name in the song title "Santa Claus is Comin' to Town" is misspelled as "Clause."
