Other mistake: In the beginning of the movie, when Jan and Todd watch Ireland go against Germany, the scoreboard reads 2-2 for the "Boot Line Chug," implying a best-of-five bracket. However, when the Americans compete, it is merely the "Line Chug" sudden death in a best of seven event.
Suggested correction: The rules simply changed in the year between the 2 beerfests. The MLB World Series used to be best of 5 but was changed to best of 7 in 1985.
Other mistake: Denning and Grim are chasing the puppies through a field and their car runs out of gas. They sit there and talk for a few seconds and then they get the net, though in the next shot, when they are chasing the puppies on foot, they are only a few steps behind them.
Other mistake: After Todd phones Bob and tells him about the rinkle-dinkle regarding Larry's request, when the Munros sing about the Rolling Turd, in the close-up, as the RV drives past the camera, the sideview mirror is deliberately turned all the way around so as not to see the crew's reflection. This also occurs when Bob asks the Trooper about the traffic jam around Mt. Watson. (01:14:00)
Other mistake: When Buddy reaches inside the fuse box, after Finch puts snow in it. They cut right from him pulling it out to show his hands and there is a snowball in his hands. We do not see a snowball in the fuse box and he does not have time to shape one.
Other mistake: When Julia is trying to pop her zit with a plier, it's obvious she isn't applying any pressure.
Other mistake: When Helen kills the zombie bully she fires 9 shots from a 6 shot revolver.
Other mistake: In the opening credits, it says co-starring (in alphabetical order), however Charna Halpern is after Tim Walsh and before Debra Wilson. She should be listed after James Grace.
Other mistake: In the very beginning of the movie, we first meet John Tucker as he makes a slam dunk. Obviously, this would be worth 2 points. However, if you watch the referee behind John, he signals a 3 point shot. (00:03:00)
Other mistake: During the Dance Dance Revolution challenge, the challenger should have won. Jeff does some outlandish freaky dance moves, which in no way correlate to the arrows that are on the arcade screen. The arrows that he hits, aren't even the same ones that register as being hit up on the screen.
Other mistake: In the beginning, Aquamarine exclaims "My fingernails! They've never been this color before!" But her nails don't actually change colour until a few shots later.
Other mistake: When JB is leaving the cafe, he pays money, but he did not buy anything.
Other mistake: Why is it that, at the wild party, the guys at the barn are shocked to find out how long Simon's "unit" is? Didn't they see it when he showed up to the fancy ball with only a black tie on?
Other mistake: The girls are invited to the cool party where the cool kids go. They are discussing it in the hallway, pitching a non-existent boat party. Throughout the scene, extras just keep walking back and forth to make the space look like a busy school. A guy with a loud green Hawaiian shirt carrying a clipboard is particularly noticeable. (00:02:30)
Other mistake: When Mike stops time to hit his boss, he starts getting off the desk. There's a bottle of water on the desk, however, the water is moving around from Mike moving on the desk. How can the water move if time is frozen/paused?
Other mistake: When Jenny and Matt first enter his apartment, the deadbolt on the door is intact. Later, when Professor Bedlam's minion kicks the door open the plate and deadlatch are missing. The act of kicking the door open might destroy the striker plate in the door jamb, or it might blow the entire lock body through the door, but it couldn't neatly remove the plate and bolt alone.
Other mistake: In the first microwave scene, Roddy press the random buttons (4,6,5,3,2) but the microwave only shows 3 seconds, and the popcorn already popped within those 3 seconds. (00:02:55)
Other mistake: Just after Paula shoots the last of the Devil Babies, as he turns and says "Aw man", his back is devoid of paint from the fatal volley.
