Continuity mistake: In the beginning during the Indiana Jones parody one of the men pulls a gun on Weird Al with his left hand. Then Al lashes his whip, slicing his arm clean off. Then we see a RIGHT arm fall to the ground, gripping the gun in its hand. [Explanation: The live scene was shot one morning, and the actor who had his arm whipped off was cleared and went home. After lunch the prosthetic arm was delivered, and it was the wrong arm. They were on such a tight budget that they couldn't delay the shot, and flipping the negative (so right becomes left and vice versa) wasn't an option because the scene with the small pond had already been shot, and couldn't now be shown in reverse. This is from Weird Al's website, www.weirdal.com.] (00:01:40)

Visible crew/equipment: Just after our two heroes have been fired from Big Edna's, a black Porsche crosses the screen treating us to a perfect reflection of the sound man, complete with boom and Sennheiser microphone. Really, it's that clear. (00:07:55)

Continuity mistake: As Philo sets up his camera in Fletcher's office, he has a pencil in his mouth. In a subsequent shot, the pencil is gone. He did not remove the pencil as he was working on the camera the entire time. (This is even mentioned in the DVD commentary.). (01:00:15)

Continuity mistake: While Uncle Harvey is in the pool, there are several items lined up behind him. Notice that the sandals are on the extreme left. After Harvey falls in the pool, the sandals hop over to the extreme right, next to the radio. (00:56:00)
Suggested correction: As with many "mistakes" posted for this film, this takes place during one of George's silly fantasy daydreams. Anything can happen - if a left leg had landed on the ground, it still would not be a mistake.
I think this is a very weak correction. When it comes to things like dream sequences, an Occam's razor approach is probably best: the simplest explanation is probably true. As in, unless it's blatantly done for effect, a mistake is probably just that... a mistake.

Four other "mistakes" in this film have been corrected, on the grounds that they occur during silly, fantasy daydreams by George. Check the corrections page on this site. Why should this "mistake" be any different?
If you check the timestamps, those corrections were from nearly twenty years ago. The system was different at that point in time. Basically, anyone could submit a correction, and there was a good chance it'd be accepted, even if the correction was incorrect. The current system, which was implemented a few years ago, is better in a way because it allows voting and debate. The fact is, as was pointed out, even Weird Al has admitted it was a mistake. Suggesting that dream/vision/fantasy sequences are completely exempt from mistakes is just plain silly, and a slippery slope in a way.
