Factual error: The bullet that was fired and travels next to the rocket car defies the laws of physics. Assuming that the bullet was fired parallel to the ground, the bullet should remain in the air for the same length of time as it would take to drop the bullet from the same height. The bullet in this scene remained in the air for a much longer period of time.
Continuity mistake: Tracey's hair in the helicopter jumps from under the headset to falling around her face and back again.
Factual error: As Whoopi Goldberg and her daughter stop the rocket car, the engines on it are clean and shining. After driving through all the brush, not only would they have been very dirty and filled with plants, they would probably have been FODed (Foreign Object Damage) out and quit running long before it ran out of fuel.
Revealing mistake: When Vera and Merill are talking to the squirrel lady, whenever you can see the ground behind the squirrel lady, near one of the cages, you can see a squirrel that is obviously fake. It is not moving at all and looks like it is carved from wood.
Continuity mistake: When Tracy and Nick arrive at Tracy's ex-boyfriend's house in her helicopter, Shawn's (Tracy's ex-boyfriend) mini-pool falls apart and water spills everywhere. He and the girl are both submerged in water and go flying. About 10 seconds later, he runs to his car in a collared shirt and he is completely dry.
Continuity mistake: When Whoopi and her daughter arrive at the Silver City station, they are in a bus. The bus passes by the station, and you can see that they are fairly close to it. When they get off the bus and run towards the station, they are much farther away.
Continuity mistake: When Jon Lovitz's character wipes Eva Braun's lipstick off him and onto the steering wheel, it appears to be dark red. But after the crash and the formation of the "Hitler mustache", it is black.
Continuity mistake: Tracy throws a wrench and other things onto her (soon-to-be-ex-) boyfriend's truck. Several dents appear, including on the roof. She also drops a can of orange paint which spills up the windshield. However, for the remainder of the movie after this scene (as her boyfriend drives it away and later Tracy throws him out and takes it herself), there isn't a single dent left on the truck. Not just as she chases her boyfriend, but for the rest of the film.
Continuity mistake: There is a shot of Blaine as he lays on the Cadillac's roof during the balloon/cow/keymaker/car chase. This shot is specifically for when Blaine snaps the hood ornament off of the Cadillac by accident, then stares at it in his hand. In the next shot of the car, the ornament is back on, and it stays on for the remainder of the scene.
Revealing mistake: At the end whenever we see a shot of the large crowd from the stage point of view look closely.You can see how the image of the crowd has been tiled because people are transparent. They must have filmed a small section of the crowd then duplicated it to make it appear that there are thousands of people there.
Factual error: When the brothers are both in the pond and one of them comes up covered in pond weeds, notice a few places on his body, for instance the side of his head, he has a plant attached to him called Water Hyacinth. This plant not only does not grow in the South West, but also floats and you can see that there are none floating anywhere on the pond, especially in the middle where he landed.
Factual error: During the monster truck scene, the brothers line up their car with others that are to be crushed. All of the cars have their windows and antennae intact. In a real crush, they would all be removed for safety purposes, ie. No flying glass and pierced tires.
Factual error: You can see Joshua Trees many times during the movie (During the Rocket Car scenes, for example.) There are no Joshua Trees outside the Mojave Desert.
Continuity mistake: When Seth Green and his brother are chasing the keymaker, they fly over two embankments. In both shots, upon impact they break the A-pillar in the car, resulting in the nose of the car pointing upwards and the area directly under the windscreen bent down, common in a stunt like that. In the next shot of them racing along the paddock, the car is perfectly normal.
Deliberate mistake: In the infamous coin toss scene, Cuba's call is disputed. However, it appears that the coin on the ground is in fact in agreement with his call. However, he explains later that they use a special commemorative coin that is hard to read as it may have what appears to be a head on both sides. Therefore, the coin may have had a head come up, but it was agreed that that side would be 'tails'.
Revealing mistake: When Seth Green is taking money out of the Donation Jar to put in Gambling Machines, he is not getting any money out and pretending to put coins in.
Revealing mistake: When Blaine is getting Duane to put the money in the bag, you can see at one point he tries to stop himself from laughing. This is because on the special features of the DVD there is a 6 minute long outtake where they both keep laughing on this take.
Revealing mistake: After Mr. Kameechi throws up on the airplane as part of a bet, he puts the "throw up" bag down on his tray. If you look closely, you will see that the bag has absolutely nothing in it (it's flat).
Deliberate mistake: There is a clear shot change as the monster truck lands on Blaine & Duane's Cadillac. One minute they have JUST fallen out of the car and fell to the ground, and the next they are at least five feet away and running, full-speed.
Continuity mistake: At the end when the highrollers are aboard the private jet, the outside shows a small plane, but the interior shot shows a huge plane with tonnes of overhead room.
Answer: They say, in turn: "Hello, Ladies!" "We saw you runnin' on the highway" "Without a chaperone" "Somebody has some s'plainin' to do".
