Continuity mistake: At the start of the movie, where Jim's father comes into the dorm room after that guy unlocks the door for him, he comes in, and drops the six-back of beer then sees what Jim is doing, at an angle. When it drops to the floor, it is standing. Wouldn't it be on its side? (00:03:00)
Revealing mistake: When Jim's Dad walks in on him and the girl having 'goodbye sex', Jim scrambles around trying to cover himself. At one point, as he's going from the floor to the bed, you can see the string bikini or whatever he's wearing so that he doesn't accidentally expose himself. (00:03:20)
Continuity mistake: When Jim is talking to his dad at the start about being embarrassed, his arm moves depending on the shot. (00:03:20)

Continuity mistake: Jim's mom drops the Tupperware of food with the top facing up, and when it lands, the top is facing down instantly. (00:03:30)
Continuity mistake: In one of the first scenes of the movie when Stifler is talking to Oz in a classroom, you can see clearly that Stifler has a cold sore on his left side of the bottom lip. The camera changes to Oz and later on when shows Stifler again the sore is gone. (00:05:10)

Visible crew/equipment: At the start of the party, when Stifler walks to the door, in the window above the set lights are visible. (00:09:50)
Continuity mistake: In the scene where Stifler is chasing Finch down the stairs at Stifler's party, Jim separates them both while holding a cup in his right hand, which he switches to his left, then in the next shot from a different angle it is back in his right hand. (00:14:30)
Continuity mistake: In the scene where the Asian guy is taking a piss of the balcony at Stifler's party, you see Stifler and his girl stand up when the pee hits the pillow. Then the camera is switched to the balcony where the Asian guy and a girl are talking. Then again we see Stifler and his girlfriend, but now the pillow is dry again. (00:16:30)
Continuity mistake: At the party at Stifler's the other guys are playing cards at a table and the amount of cards lain down, the numbers and suits of the cards, and the position the cards are in change with every shot, and when the cops show up there are no cards at all on the table. (00:16:40)
Visible crew/equipment: When Chrissie gets knocked out by the plant pot, you can see a safety mat conveniently placed next to her. (00:17:00)

Continuity mistake: In the scene where Jim, Oz and Finch are sitting in front of Dog Years after the call from Nadia, you can see some people in the back. When Kevin shows up the people disappear. The camera moves away for a moment and after it comes back, the people have reappeared. (00:21:35)
Factual error: The movie takes place in Michigan, however when the boys first arrive in town, a sign reading "United States Post Office Seal Beach, California 90740" can be seen in the background. (00:21:55)
Continuity mistake: When the boys are packing the pick-up to go away, Jim puts a backpack on the rest of the luggage in the middle. Next shot it is at the side of track. No-one had time to move it. (00:22:10)
Visible crew/equipment: When the guys arrive at the beach house, there is a shot of the pick up going by the house. If you look, you can see the film crew reflected in the paintwork of the blue pickup. (00:23:50)
Continuity mistake: In the scene when the guys are painting their first house, you see Stifler talking to Finch, and Stifler is holding a bottle by the cap. In the very next shot, he is holding it by the bottle itself. You never see him change his grip on the bottle. (00:25:20)
Continuity mistake: When Finch is explaining to Stifler about having sex for days, both Jim and Oz's hands change place instantly between shots. (00:25:50)
Chosen answer: Yes. That's the point of the theory. Men multiply the number of women they've had sex with by 3, women divide the number by 3.
