In the Scene after Rex opens the garage door to see if the Judge is gone, he starts smashing the garage door. In one scene the bottom of the door is bent inwards, the next it's not, then it is again, and finally when he knocks it off the runners, the bottom is like new again.
When Lance and Ezekial are in the horse wagon, you see Lance's arm shift between shots. One time you see around Ezekial then his arm is on his side (or somewhere in the vicinity but not around Ezekial). It does shift a few times.
When Ian and Lance get arrested by the police and put into jail, Lance has to give the police his cell phone and watch (and his handcuffs). Ian is supposed to do the same, but when they come in to the arrest, Ian still has his watch on.
After leaving the trailer and being chased through the corn by the jealous boyfriend the corn is green, later in the film a corn field is completely brown.
In the patio scene as Ian leaves Lance's party, the different shots of the door have people entering and exiting but depending on who is focused in the shot people disappear.
Seth Green's character when he finds the GTO stranded on the road mentions that it is a 1969 GTO with a 455 HO engine. The 455 was not an option till 1970. The largest factory engine the GTO could have in 1969 was the 400.
There's no Big Boy in Tennessee. They were Shoney's Big Boy until Shoney's dropped the Big Boy name.
When Ezekiel is towing the Judge by a rope from his wagon, the car stops as suddenly as the wagon even though nobody is in it to apply the brakes. It should have crashed into the wagon.
In the scene after Lance's party, Miss Tasty asks Ian over the Internet about his football practice. Ian answers with "Awesome.", but when he presses enter, it appears without the punctuation mark.
The indentation on Ian's head from the radiator cap should read "hot" backwards, not the correct way.
At the credits when showing the pictures, the one with Lance is about to cut his hand with the saw, you can see that the saw has no teeth.
In the bathroom when Ian unknowingly reaches for toilet paper and touches what presumably is the genitals of the man in the adjacent stall, a light-pink prosthetic is clearly seen under the toilet paper.
On the Unrated version, when director Sean Anders is talking at the very beginning of the movie, he says "these tits are good," but his mouth doesn't move. (This was possibly done purposely, as the intro sequence was intended to be rather absurd.)
When Rex is talking to Ian in the Blaze Room and lets him borrow the car, he tells Ian to fill the Judge's tank, though he is mouthing something different.
This is heard in the unrated version. In the unrated version. You'll hear quotes from different characters and the mouth movement and the voices don't match. This is rather absurd.

Filming equipment and crew can be seen in reflection from the convertible as they are driving past during the first part of the trip to Knoxville.
Cameraman reflected in Rex's sunglasses and near the chrome bummer.
As Ian and Lance pull out in the GTO, the reflection of crew equipment can be vaguely seen on the side of the fender.
The trio tries to outrun the hitchhiker, who responds by urinating on the car; as Ian rolls up his window, the camera's reflection can be seen for a split second.
Reflected on the GTO as the trio pull up to a local dentist office.
Although the beginning of the film is set in suburban Chicago, when Rex is driving Ian to work at the mall, palm trees clearly are visible in the background immediately before a jump cut to the mall. (The movie was filmed almost entirely in south Florida.)
In the video montage of the beginning of their trip (played to MGMT's "Time to Pretend") you actually see shots of Indianapolis before you see shots of a popcorn bin in Boone County, Indiana on the side of highway 65 south. This is incorrect because traveling south through Indiana, you actually would go through Boone County before Marion county, where Indianapolis is located.
