How the Grinch Stole Christmas (2000)

Continuity mistake: After the Grinch stole all of the presents, Officer Wholihan gets into his police car and drags the mayor's bed out of his house. When the bed smashes through the window it breaks the top off the middle post of the bed. Then when it comes back to the shot of the bed it's been fixed.

The Grinch: The nerve of those Whos. Inviting me down there - and on such short notice. Even if I wanted to go my schedule simply wouldn't allow it. 4:00, wallow in self pity; 4:30, stare into the abyss; 5:00, solve world hunger, tell no-one. 5:30, jazzercize. 6:30, dinner with me. I can't cancel that again. 7:00, wrestle with my self-loathing; I'm booked. Of course, if I bump the loathing to 9 I could still be done in time to lay in bed, stare at the ceiling and slip slowly into madness. But what would I wear?

Trivia: When the Grinch takes the table cloth from the table, everything on the table was supposed to fall off. When Jim Carrey yanked out the cloth however, everything stayed in place. Jim immediately walked back to the table and improvised knocking everything off and then knocking the table over.

Question: In the beginning, there is a watchman that announces "Another minute closer to Christmas!" as each minute ticks off a countdown clock. Assuming that each panel (days, hours minutes) is on a revolving wheel of some sort, how can the three wheels work correctly in such close proximity to each other? Granted, only the minutes part moves for the sake of the story, but it still begs the question.
