Corrected entry: In the hotel, how does Richard unzip his boxers with his hands shown on the curtains?
Corrected entry: When Richard's hair is blown back by the engine fan, the fan must have been mounted backwards because the fan is supposed to blow air ON the engine, not in front of it.
Correction: The fan on the motor is correct. Radiator fans are designed to cool the radiator - not the motor. Next time you park your car in hot weather and the fan comes on, feel the warm air being pushed through the radiator from behind out towards the front of the car.
Corrected entry: When Rob Lowe is trying to shoot the trucks at the Callahan factory, he gets back into his car and then gets strangled by the seat belt. When this happens, the car door closes. He then fires a shot of which the bullet hits a sign which, in turn, breaks the guard dog's chain. When the dog jumps into the car, the car door closes again.
Correction: The door never closed the first time, you can see the door fling back open in the first shot, then the dog jumps in and the door closes all the way.
Corrected entry: When Tommy Boy is on the phone with Michelle, Michelle says that his dad has never sold 1,000 brake pads in Oshkosh. Big Tom could have never sold that much because he died before they started to sell the brake pads.
Correction: It should also be noted the bank loan was to build a new brake pad division and the these were new and revolutionary brake pads. The company always sold brake pads. Big Tom gives Tommy a whole catalog labelled "Brake Pads" to look over, indicating the sale a wide variety of them and at the meeting after Big Tom's death, Tommy says Richard knows more about brake pads than anyone in the room. Again, indicating they've sold brake pads when Big Tom was alive.
Corrected entry: When David Spade first picks up Chris Farley he tells him he has just put a 440 with a 6-pack carburetor, but later when the hood flies off you can plainly see that it has a regular 2-barrel carburetor and air filter.
Correction: He lied, he has no friends and is trying to impress.
Corrected entry: In the scene where Tommy's father is showing Chris Farley his new office the name on the door is "Thomas Callahan III" but when Chris Farley is introduded as the new president of the company at the end of the film, he is introduced as "Thomas Callahan, Jr."
Correction: There's no mistake here, his full name is Thomas Callahan III, but he is referred to by his friends as Thomas Callahan Jr.
Correction: When Richard unzips his boxers only one hand is shown. His left hand is not shown holding the curtain, he must be holding it with his leg or his shoulder.
