Corrected entry: Although the scenes showing poor Andy's erection spitting up urine onto his face when he tries to pee are pretty funny, they're also impossible. When a man gets an erection, a little plug moves into place to block his urethra, since men have only one tube for urine and sperm. Which means a man can't urinate when he's fully erect.
Corrected entry: When Andy crashes through the billboard, pieces of drywall and chalky dust can be seen all over the place. Real billboards aren't made from drywall, which doesn't last long in the rain. Also, if you freeze-frame just before he crashes through the second side of the billboard, you can see where the drywall was scored or pre-cut to facilitate the stuntman breaking through. (02:01:25)
Corrected entry: Near the end of the actual movie - BEFORE the montage - Andy's chest hair has miraculously grown completely back, with no evidence that it had been waxed. Even if some hair had grown back, there would have been a marked contrast (and a noticeable dividing line), between the parts not previously waxed and the new growth in the waxed area.
Corrected entry: Near the beginning of the film, Andy and his neighbor discuss their plans to watch "Survivor" together the following night. The subsequent dialogue at Andy's office makes it very clear that the current day is Monday, and therefore tomorrow would be Tuesday. However, "Survivor" airs on Thursday.
Corrected entry: In the scene where David is chasing Andy around the building after everyone found out he was a virgin, Andy tries to open the back door to smart tech but finds it locked. But when Haziz comes out for a smoke he easily opens the door after being asked repeatedly and forcefully to leave. (00:17:30)
Corrected entry: Towards the end of the movie when Andy and Trish have decided to wait 20 dates to have sex, You see the calendar on his fridge showing the dates they've had. The calendar is very strange in that it only has 6 days in each week, and thus has 6 weeks in that month. There are numbers on every day of the calendar, so its not that the calendar combine weekends into one box or anything.
Corrected entry: When Andy's friends are playing Mortal Kombat, the arena that they are fighting in changes. In one shot they are in one area ("man, there's a dead body in my way"), then all of a sudden they are on a different level. It isn't a lower level of the game (which that game is known to have), because they started on the lowest level.
Corrected entry: For understandable reasons, when we cut to the close up of Andy's face during the waxing scene, no strips are actually taken off, though he reacts three times. You can tell because no additional hairless sections are evident when we cut back to the full shot, and because seven patches are taken off during the entire scene, which matches his body as well as the number of used wax strips lying on the bed. If he had actually been waxed during the close-up, he would have had ten patches.
Corrected entry: During the chest waxing scene, the woman doing the waxing is really laughing after the first pull. She manages (barely) to control herself during the next ones.
