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: 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: 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: When the girls are introducing themselves, Patty is drinking from a coffee mug. When she shatters the mug, nothing spills out.
