Continuity mistake: When Adina is screaming for Dave as the "wingman", you can see that the window is broken even though Jimmy hasn't been thrown through it yet.
Continuity mistake: If Spence was supposed to steal the money right after Dave looked in the safe, then Dave should have been on the tape; instead it jumped right from Adam and the Tri-Pi to Spence stealing the money.
Continuity mistake: When Michael Rosenbaum is talking to his little bro near the end of the movie, he is eating with silverware, but when the shot changes, the silverware is not in his hand and he is making gestures.
Continuity mistake: When Daisy and Adina have their dildo fight, at first only Adina has two dildos in her hands. When the camera goes back to Daisy, without her having any time to pick something up, she also has a dildo in her hand.
Continuity mistake: The first time Dave is showering with Leah, just as he is about to leave, he has a lot of soap on his chest and stomach, but when he runs out of the shower he hardly has any. There wasn't enough time with him running for it to have all been washed off.
Continuity mistake: During the football game, the mud streaked on Katie's (the loud girl) face: when she yells, "Times out, time's out" it is in a right angle on her left cheek. After Pattie makes the touchdown, Katie doesn't have any mud on her cheeks at all.
Continuity mistake: During the middle of the film where the music is that song "Good Girls Don't But I Do", there is a selection of shots of the guys dressed as girls in which they are wearing clothing that they don't actually put on towards the end of the film (Adina in the tight brownish pants and pink shirt, Roberta in the denim dress, Daisy in the red dress and sweater). That day Adina was actually wearing that green shirt with the ruffles.
Continuity mistake: In the scene where Adina is in the hallway and Jimmy is with her, you can see a girl with a grey top walking up the hallway towards them. A few seconds later, you can see her further back and walking towards them again.
Continuity mistake: At the end of the Powder Puff football game, the announcer says that the play will be the last play of the game, which is why it's so amazing that the DOGs win in the last seconds - but the score board that counts to 14 says it is only the third quarter. Also, it says that they have 10 yards to go, and Patty ran a lot farther than 10 yards to score the touch down.
Continuity mistake: When Doofer is breaking into Adam's footlocker in the flashback, the stuff on top keeps moving even before he touches it: look at the right sneaker.
Continuity mistake: The first night the boys become girls, they go to the all trim party and Adina goes off to find the tape in his "old" room. When he gets there, he's hassled by Jimmy. When Jimmy takes off his robe, (when he's blocking the door), they have 2 different angles, and the one facing Jimmy, you can tell that Adina is trying not to laugh, but the other one "she's" perfectly disgusted.
Continuity mistake: In the scene where Michael Rosenbaum and Barry Watson begin to fight with the dildos, Michael Rosenbaum is wearing white bikers under the skirt when thrown on the couch. The fight continues outside and he is now wearing black bikers under the skirt.
Continuity mistake: When the girls are introducing themselves, Patty is drinking from a coffee mug. When she shatters the mug, nothing spills out.
