Continuity mistake: In the opening credits, the guys are standing full depth in the giant shopping cart. When they get to the bottom, the cart most noticeably has a platform halfway down that the guys are standing on when they get thrown out. [It is mentioned on the cast commentary (by Bam) that they needed to raise it up because they were afraid of jumping out from so low down in the trolley. Still a mistake, but that's why it's there.]

Other mistake: In the Rube Goldberg Test scene, read the subtitles when Rip Taylor is talking. In the actual movie (where all we see is Johnny Knoxville coming out of the catapult) the subtitles have him saying "Oh, child." at one point. In the extras (where we see the complete Rube Goldberg Test), the subtitles show Rip saying "Oh, John." for the same line.
Continuity mistake: In the opening shopping cart scene with the cast, you can see on a wide shot that Wee Man is in between Johnny Knoxville and Bam Margera, but in the next scene when Bam hits Dunn you can see Wee Man is sitting in the front of the cart in the seat, in the next wide shot Wee Man is back in between Knoxville and Bam again.
Revealing mistake: In the scene in which Ryan Dunn jumps into cacti with his BMX bike Preston Lacy is supposedly yanked off of his couch by the momentum of Ryan's jump. However, if you look closely in the background it is obvious that Preston Lacy hardly moves at all from Ryan's jump and the effect was edited in later. [In reality, Dunn barely even movied Lacy. The crew reshot it and pulled Preston off the couch by hand.]
Continuity mistake: In the burglar scene Bam has no hat on. After they crash through the ceiling, still no hat. As Bam is picking up the diamonds, right after Johnny slaps him, a hat appears out of no where. Then as they run out, Bam has no hat again. Yet when they exit the building, Bam's hat is back on.
