Revealing mistake: After the roof blows off the cabin, the hail starts falling inside the cabin. It is fairly obvious that the hail is just being poured onto the cabin. Its most noticeable just after the hail starts falling on the cabin, there is a shot taken from inside the cabin you can tell by the night sky and some of the trees outside that there is no hail in the distance.
Continuity mistake: When the boulder is coming down, the front door is open. When we get a shot of the front of the cabin, the door is now closed. However, the doorknob switches from being on the left to being on the right. We also see there is nothing hanging from the porch roof. Before Mike and Steve crash through, we see the front again and the doorknob is back to the left and there's a metal star hanging from the porch roof.
Continuity mistake: When the boulder hits the cabin and Mike falls out the front door, he's rolling, almost off the door, and on his side, with his back close to the rocks. There also is nothing on the back of the door. When it cuts to the close up, Mike is now face down on the door completely, with a dartboard on the door.
Continuity mistake: Near the end of the movie, while at the Governor's mansion, Drake Savage (played by Gary Busey) is in a tree with a rocket launcher. He jumps out of the tree and lands without the rocket launcher. In the next scene, he jumps onto the stage and he has the rocket launcher, which he left in the tree.
Revealing mistake: When Mike is on his way to go vote and he falls down the hill, he gets to a spot where it isn't steep enough for him to be moving fast. If you look closely, you can tell that the editors of the movie fast-forwarded it to make it look like he is rolling down the hill really fast.
Continuity mistake: When Chris Farley is at the top of the hill, he then slips and falls for a little while. He finally gets to a place to stand up, and his blue shirt is covered in dirt. He then falls again, and when he reaches the bottom, he stands up, and his blue shirt is completely clean.
Continuity mistake: When Mike is playing football on the field, he scores a touchdown, and throws the football down. Then it cuts away to the kids complaining, then back to Mike, and the lost football is in his hand. It cuts to a larger view of the scene, and where's the football? The camera cuts away again, and then back to Mike and his team. The football is once again in Mike's hand.
Continuity mistake: When Governor Tracy is chopping down the tree, we see the pre-made cuts (that are suppose to be there). After her 2nd chop the shot changes to her family, but when it goes back to her, there's a new notch in the tree and it's not from her chopping as we don't hear her chopping. When it cuts to the tree the final time, after she says "don't let anyone tell you your job is easy", there are more chop marks that aren't from her.
Continuity mistake: When Drake sneaks up on Steve while he is urinating on the tree, he turns Steve around, and as happens in many films when someone is interrupted while urinating, his genitals are magically back in his pants. You can then hear Steve urinate on the ground a couple times as Drake continues to intimidate him, which wouldn't be possible if his genitals were back in his pants.

Audio problem: The last scene begins with Al and Mike walking towards the plane speaking. Al asks "are you sure you don't want a job on my staff?" Mike then responds by stating; "you know what Al... I don't really think I'm cut out for politics." Al then is heard laughing at this. It is very clear the audio laugh is actually that of actor David Spade and appears to be placed over a most likely silent smile of Al.
