Revealing: In the parade scene, not only are people wearing long hair and bellbottoms, but late '70s vehicles can be seen passing or parked in the background. Also in one shot, behind the marching ROTC, a camera rig can be seen in front of spectators photographing the parade.

Continuity: In the Classroom scene, Donald Sutherland takes a bite of the apple and a split second later in the next shot, he has nothing in his mouth.

Continuity: When one of the Delta Frat Guys is drinking beer in the frat, in his close up he is holding a mug by the handle, in the reverse shot he is not holding the handle.

Continuity: In the cafeteria scene, Kevin Bacon's character sits down twice.

Continuity: When Pinto and Flounder visit the Omega house in the opening of the movie. Notice the girls coming down the stairs. In the first sene they are there, the second scene they are not, then they are.

Continuity: The scene where Flounder tosses the box of marbles into the street to trip the ROTC cadets during the parade. Look at the background parade audience as they go into fast forward along with the action of the marbles...

Continuity: During the parade, Flounder dumps the bucket of marbles towards the camera, and they are all clear glass marbles. When the ROTC members slip and fall on them, the marbles are red, blue and yellow.

Continuity: During the parade scene at the end of the movie, there are shots of the street that it will take place on, and there is a view of a (misspelled) "Homestead Ferniture" store in two different shots. When the parade is actually taking place, the store is changed to (correctly spelled) "Homestead Furniture". Several shots after that, it changes back to "Homestead Ferniture"

Continuity: When they're at the man's house who offers them some pot, you can see that he's petting a Siamese cat. But when he stands up to go put the blinds down, the cat is gone and he never moved it off his lap.

Revealing: On the day the house is being emptied, after Bluto finishes the Jack Daniel's and tosses the bottle, there are no Jack Daniel's labels on it.

Revealing: When Bluto uses the banner to jump from the building, you can plainly see that his weight is being supported by a safety rope and NOT the banner itself, which is actually slack during the stunt.

Continuity: During the parade, we see Nedermeyer leading the ROTC cadets, who are carrying M1 rifles. Later, during the riot, we see Nedermeyer take an M1903 rifle off a cadet and use it to shoot at Flounder.

Continuity: When they show Flounder's face on the screen they throw beer cans at it and it gets soaked. When Otter gets up it is completely dry.

Factual error: The Coca-Cola sign on the pop dispenser in the cafeteria has the "Dynamic Ribbon" device as part of the Coca-Cola trademark. The movie is set in 1962. Coca-Cola didn't start using the Dynamic Ribbon on its trademark until 1970.

Visible crew/equipment: During the scene where Otter is hitting golf balls at the ROTC cadets, Niedermayer is wearing a highly polished chrome helmet.  In at least one shot, you can see a movie light reflected in it.

Continuity: When they are getting the girls from the other college, when the first girl comes down the stairs her broach is on the left of her top. When she is sitting down, the broach has moved to her right. It changes back to her left again after this shot and for the rest of the film.

Continuity: From Double Secret Probation DVD - "When Bluto is placing the ladder outside the sorority house, there is a large awning between the two windows and it would be impossible for him to "jump" the ladder from one window to the next."

Other: Before the Homecoming Parade, the mayor hands Dean Wermer a gold whistle. Watch the gray haired man sitting in the bleachers. (Look over the Mayor's right shoulder.) Who is this man gesturing to?

Revealing: During the scene where the Delta boys are looking at slides of the recruits from the evening, Otter steps in front of the screen to defend Flounder. Notice that he is standing directly in line with the projector to the screen and there is no shadow on the screen nor is part of the slide projected onto his chest.

Continuity: In the cafeteria, Bloto puts stuff on his tray. Before the cut his bunch of bananas are on the side of the tray. After the cut the bunch is on the other side.
