Goofs

When Lars is tied to a tree, his tank top is ripped. Later, there is no sign of the tear.

The nurse's hair color varies throughout the movie.

When Tony first comes out, the camera man follows him all the way to the front row. But moments later he is at the back with a red light on the camera that turns off and on in different shots.

The bug zapper in Tony's cage drastically alters positions as scenes change.

Tony smashes the glass in the aisle of the cafeteria and walks over it. It has been completely swept to the side by the tim he back-flips down it.

The equation they have at the last race is not 11. It's not even a solvable equation as it only has one side (the other side just reads "?").

Harvey Bushkin says that "sometimes things don't work out the way you planned and in those situations you file Chapter 9 bankruptcy," however Chapter 9 only applies to municipal bankruptcies and could never be filed by an individual or company.

Gerry is 11 years old but he is shown at the beginning to be in high school, coming out of a classroom.

The Bushkins would not have filed For Chapter 9 bankruptcy. Chapter 9 is for municipalities.

In the main dorm, there is a bathroom door that says "girls". Which is fine, but the camp is an all boys campus. However, this may not be a goof - it could be rented as a girl's camp at other points in the summer.

When the boys are at their mid-movie weigh-in, Tony becomes upset as he keeps sliding the counterweight further up the scale in order to indicate that the boys have supposedly gained weight. However, this kind of scale only indicates weight when it's made level. For both boys, the scale is leaning completely to the right meaning both are lighter than whatever Tony has it set to.

During the dance with the girls camp, Jerry is seen wearing a sports coat and multicolor tie, and Nicholas is wearing a Les Miserables t-shirt. When Tony breaks up the dance he tells the staff to put the food away, and by the tables there are 2 boys wearing the same exact outfits that Jerry & Nicholas were wearing before.

When Tony is checking the camper's weights, he tells the camera man to roll, but the camera's tape deck is open.

At the end of the movie when Gerry uses the propeller in the back of the go-kart to jump over the other go-kart, it can be seen that the propeller is clearly not spinning.

When Lars stabs "The Blob", it deflates with smoke shooting out of it before the sphere ever touches it.

When Josh says "Seymour Butts" he's actually saying "Peter Fitz". Then Uncle Tony says, " Who's Peter Fitz?" and Josh's voice over is covering the answer," Anyone's Peter Fitz if you push hard enough."

When Josh mentions Seymour Butts, his lips do not match the words.

After Gerry gets pushed off the course in the go kart race and he finds his way back onto the course, Gerry's opponent says "Oh shoot" but his mouth is saying "Oh shit".

When the kid from the other camp is going down the rope swing at the competition, he looks calm and cool.. but, they have him screaming "AHH!" even though his mouth is shut.

When the cameraman is at the dance, he is drinking with another counselor, and he says, "Rock and roll," but his mouth doesn't move.

Crew reflected in the school bus door in the beginning as it leaves Gerry behind.

When the campers get on the bus from the plane, a cameraman is reflected in the bus door.

When Josh is shaving the red balloon, the entire crew can be seen in the reflection.

When Pat and Gerry are talking by the bus in the beginning, reflections of the cameraman behind them in the bus can be seen. But when they turn around and show them, they are all kids.

Tony offers Nicholas a "chocolate kiss" to lure him closer to his cage. The boys had only just been through their all-night food and candy orgy. It's highly unlikely that Nicholas would be tempted by a little piece of chocolate, given he's been able to have whatever he wants to eat for days now.

It is suggested that Pat Finley is 28. Tom McGowan does not pass as being 28.

When Tony and the campers are going on their hike as punishment for not losing weight, Tony incorrectly talks about the Greek legend of Icarus who was sentenced to push a boulder up a hill for all eternity. Icarus is a Greek legend known for flying too close to the sun. It was Sisyphus to whom Tony should have been referring.

How did Lars know somebody was peeing in the water? It's not something you can just see.
