Corrected entry: At the end of the movie when the ROTC men are in the parade twirling their guns, the second time around the first and third men on the far left row fail to twirl their guns.
Corrected entry: In the scene where Larry drops the drunk girl at her home in a shopping cart, he leaves her at the mayor's house In the next scene you see the dean talking to the mayor, with the drunk girl in the dean's house.
Corrected entry: During the parade, part of an out-of-control float crashes through what is supposed to be an auto showroom window. At the top of the window is a raised sectional door on tracks; the opening is really a garage doorway with a fake window added.
Corrected entry: When the dean's wife and the guy are starting to go at it in his room, she kicks off her shoe. It hits a glass table and you hear glass shatter, but the glass clearly doesn't break.
Corrected entry: In Dean Wormer's office, a man uses a measuring tape to compare the dimensions of the door opening and the dead horse. Then you hear a chainsaw, implying the horse was too large for the door. It might have been too heavy to carry in one piece, but by his measurements it would have easily fit through the door.
Corrected entry: When the frat house is celebrating the new pledges they are all in a bunch trying to dance to Louie Louie. During this scene Bluto is completely out of sync and is banging into everyone. While he is banging into everyone watch Boon - he is laughing and tries to cover it up by putting his beer bottle in front of his mouth.
Corrected entry: At the parade scene near the end, after the car has turned into the death mobile, D-day drives towards the bleachers and yells, "Ramming Speed." As the shot quickly changes to face the bleachers, you can see that the bleachers are empty.
Corrected entry: If all the fraternity brothers were expelled, how can they have graduation dates, shown at the end of the movie?
Corrected entry: When Dean Wormer calls the Delta lads into his office to read their grades, he congratulates Kruger for being at the top of the Frat with a 1.2 GPA. But when he reads all the grades out, Hoover has a 1.6 GPA.
Corrected entry: The name of the Fraternity is Delta Tau Chi. In the song at the end, it says "At Delta Chi, you can't go wrong!"
Corrected entry: How on earth can Bluto and his mate not know that the exam paper they are completing is different to the one they stole and studied for? They'd have to study for it - what's the point of stealing it otherwise? It is not a multiple choice exam - they are writing answers out in full. How can they not notice that the questions (and therefore the answers) are different to the ones they memorised? The day after the exam Eric Stratton announces that Bluto had stolen the wrong EXAM, not the wrong ANSWERS. Why do they have to be told later that someone 'stole the wrong exam paper'? Nobody is so stupid - or lazy - that they would not notice that they are sitting the wrong exam. In order to make such a mistake they would have to be illiterate, not just stupid. And as the closing sequence makes clear the Delta House fraternity members aren't even stupid - they are just lazy.
