Continuity: During the sales trip the two main characters stop at a gas station to get gas. during this stop Tommy bends the door back and after some struggle gets it to the normal door position. Before Richard gets back to the car however there is a shot of the door all dented up but in place. When Richard pulls the door off it falls to the ground and there isn't a single dent on it. (Also, is it me or does it seem a little ridiculous that someone that loves his car so much didn't notice the large dent down the edge of the door as he faced it while walking from the station to the car?)

Revealing: When Tommy is trying to bend the car door back you can see a wire holding the door in place so that Tommy can hit it as hard as he wants and it won't go back in place.

Continuity: In the scene where Tommy and his 'girlfriend' are sitting in the boat and about to get picked on by the kids on the shore, Tommy's Life jacket changes. One shot it's got a white line and a button on it and in the next shot, they're not there. Then the line and button show up again.

Continuity: In the "fat guy in a little coat" scene, you can see Chris Farley's reflection in the window; he's wearing only a white T-shirt. When it cuts back to him, he's in David Spade's coat, trying to rip it.

Factual error: The characters mention the airport in Cuyahoga Falls, Ohio.there is no airport in Cuyahoga Falls, Ohio.

Continuity: The deer knocks the rear-view mirror off the windshield, however, when the boys are driving down the highway and the car hood flies off, you can see the mirror again, then it's gone and then it's back again.

Factual error: You hear Richard unzip his pants when he sees the woman diving into the pool, but even before he goes to the window he is wearing boxers. Boxers are all buttoned, they don't have zippers.

Continuity: Tommy is celebrating with his father the recent engagement.  First you see them pouring the champagne, then second you hear the champagne bottle being opened.   (There is only one bottle of champagne.)

Continuity: At the end of scene 14, where Tommy is driving and the hood pops up, you can see a clear view of the motor, and there is no oil can. When they stop, after the hood gets ripped off, Richard points out the can.

Visible crew/equipment: When Rob Lowe arrives on the Greyhound, the camera starts from high and moves down. Its reflection is visible in the windshield of the bus.

Factual error: Rob Lowe gets into his red Cadillac and is strangled by the motorized seat belt - no Cadillac model ever had motorized seat belts.

Continuity: The hooks in the brake pad division (the one Tommy is fighting with) stop automatically when Tommy walks by. He turned them on, but he never turned them off. [The hooks stopped because the rest of the machines are all turned off so the hooks can't go on to the other machines].

Visible crew/equipment: Before Beverley comes out of the pool, a crew member and a boom mike are reflected in the glass door that Big Tom closes.

Revealing: When Richard (David Spade) vacuums the "moths", you can clearly see they are little balls of cotton or other material being blown by a chute of air to make them appear as if they were flying.

Continuity: When Tommy is changing in the bathroom, there is some paper towels in the sink. In the next shot it dissapears, and then it comes back along with a coat hanger.

Continuity: When Beverly is on the bed talking with Paul, in one shot her spaghetti strap is down towards her elbows. In the next shot, it is up to her shoulder. The shots moved too quick for her to fix it.

Continuity: When Tommy is changing in the small airplane bathroom, the tie that he has on before it gets stuck in the toilet is different then the one he has on after he gets it unstuck.

Factual error: When the two are travelling the country to sell the brake pads, when they go to Detroit, it is not Detroit. The Detroit skyline looks nothing like that and the Detroit road sign appears to be added/airbrushed in.

Continuity: When Rob Lowe is trying to shoot the trucks at the company, he gets back into the car and then gets strangled by the seatbelt. When this happens, the car door closes. He then fires a shot, which hits the sign, which hits the dog's chain. When the dog jumps into the car, the car door closes again.

Deliberate "mistake": The huge bruise on Tommy's face, from the board hitting him, disappears in less than a day.
