Continuity mistake: In the opening scene where Ernest is driving around the camp, he runs over both a trashcan and a tent. A few seconds later in another shot, if you look closely in the background, the tent is standing back up. It is the same tent because the trashcan is still knocked over.
Other mistake: In the scene at the lake, Stennis gets down and throws Moose, who can't swim, into the water. Then he gets back up on the guard tower. Then the "Last Chance Boys" push Stennis and the tower into the water. There is a close up shot of the tower's foot. It is about a quarter of an inch from falling off the dock. If it had been in that precarious of a position, then the man's movements and getting down and back up into the seat would have made the tower fall in before it was pushed.
