Goofs

The position of the camera on the computer goes from a tight shot on the bed to a wide shot of the room.

When Nadia removes her clothes, she is shown to be wearing a pair of bikini-style panties. However, when she removes the underwear a few minutes later, it is clearly a thong.

When Nadia opens Jim's drawer, the jar of Vaseline disappears.

When Finch, Stifler, and Kevin are watching Jim and Nadia on the webcam, they can't hear anything, but when Nadia turns on the radio they hear the music loud and clear.

When Kevin and Vicky get to their room, Kevin starts taking out candles from the drawer on the nightstand. When they are lying in bed, the candles are lit, when they are getting started, the candles are still lit, but during the last shot, the candles are nowhere to be seen.

In the credits, Mark Hoppus, Tom DeLonge, and Scott Raynor are listed for Blink-182, however Scott was not in the movie as he had already left the band. It was Travis Barker who appeared in the movie playing drums, not Scott.

In the parking lots in some scenes, cars are seen with front license plates - Michigan does not require front license plates.

The camera broadcast of Nadia is being displayed in a total different operating system. Behind the camera it looks like Mac OS 8, however the window in which her camera stream is being shown in, is Irix. (at around 1h 30 mins)

It's spelled "Penta Lax" with a space, not "Pentalax."

Although Czechoslovakia (where Jim says Nadia is from) ceased to exist as a country in 1993, Americans sometimes use the name in discussing Czechy or Slovakia, the two countries it split into.

When Jim's Dad and Jim are looking at the porn magazines, they both mispronounce the word 'clitoris'.

People often mispronounce words, even that word, and it's not uncommon for children to pronounce words as their parents do.

In Jim's room, it can be seen that there is no ceiling.

While Jim, Finch and Kevin are watching the webcast of Nadia, there are dates available on the screen, all referring to the month of July. However, being in school and preparing for prom, it would have most likely been April.

In the dance scene, the keyboard is not plugged in to AC and there are no audio cables coming out of it.

While Jim, Kevin and Finch are viewing Nadia on the web cam live, the duration of "NadiaVision" remains at 0:00:19:26 throughout.

When Finch is on the toilet, he is wearing underwear. The leg hem of what appears to be boxer briefs is visible in a side angle shot.

During the conference of the four boys at prom, there is a close-up of Kevin Myers speaking. However, in the next shot they show Oz, and in the corner is part of Kevin's face mouthing the words he had just spoken.

When Jim's Dad is showing Jim the porno magazines in his room, he lightly touches his hands together. However, the sound made is as if he loudly clapped his hands.

As Stifler is walking through the party, the visual of both his slapping of a girl's butt and his snapping his fingers do not match up to the audio.

After Kevin speaks to the girl in the blue shirt about Finch not having a date for the prom, when she walks away he says "Oh, man!" But his lips are not synchronized, he is saying something else. Most likely, his lips are moving as if to say "You're welcome" after the girl has said "Alright, thanks."

When Stifler is puking in the bathroom, Jim walks in and what is heard is, "Damn, Stifler, what'd you drink?," but he only says, "Damn, Stifler."

When Finch is running for the restroom, the mike wire is visible under his shirt.

When Heather and Oz are in his dad's food shop, the light from the camera and some of the crew can be seen behind Heather when she is sitting at the counter.

When Jim is walking towards Nadia, a C-Stand is visible on the left.

The bottom of the take marker can be seen at the top of the screen for a moment while Jim talks with Michelle in History class.

A hand is briefly visible during the webcast as Jim's shirt falls off the webcam. It is actually being dropped in front of the camera.

During the first lacrosse game, Mexican Fan palms can be seen in the background. These are the famous palms all over Beverly Hills. They are everywhere in Southern California, but do not grow in Michigan.

Set in Michigan, at one point a parking lot full of cars with California license plates can be seen out a window.

In the part where Vicki and Jessica are talking about a long distance relationship and sex, for a second a microphone is visible hanging from above.

After Oz first sings for the jazz choir and comes to talk to the other guys, a microphone can be seen above them a few times.

In the "pie scene," Jim's mother's note reads "Apple - you're favorite." It should be "your favorite."

In the library, the sex manual is hidden under the classification "982.1 Fluid Dynamics." Under the Dewey Decimal System, 982.1 is History of Argentina; fluid dynamics is 532.

In a series of scenes right after the guys make the pact, Jason Biggs can be seen writing with his left hand while Oz watches TV. However, he can be seen writing with his right hand elsewhere in the film and actor Jason Biggs is right handed.

While bragging to his friends in the locker room, Stifler says that girl called him and asked for his number. While he may very well be lying, it makes no sense for someone to call someone and ask for their number as having their number is clearly a requirement for calling them.

Jim's Dad tells Jim he will leave the porn 'books' in Jim's drawer, but they are magazines, not books.
