Visible crew/equipment: When Bluto is watching the sorority girls have their pillow fight and he falls down with the ladder, you can see him land on a grass mat that is cut into the lawn. It's funny because you can see the grass push in.

Factual error: The car Flounder drives is a 1964 model, built beginning late in 1963, but the events of the movie take place in 1962.

Continuity: During the classroom scene, Donald Sutherland writes the word "Satan" on the board. In the first shot, the "t" in Satan in directly over the crease on the chalkboard. In the next shot, it is clearly on one side of the crease.

Factual error: In the scene where Pinto buys/shoplifts food from the grocery store and meets the Mayor's daughter, the cash register has an LCD display. A little too futuristic for a flick set in '62.

Continuity: When Bluto is looking through the window of the girls' bedroom, the shot from behind him shows his shoulders are just above the window sill. The shots from inside the room show him to be a lot higher than this.

Continuity: In the scene where Pinto is making out with the Mayor's daughter, as she sits up on him so she can unhook her bra, he starts to slide his hands under her bra right before she passes out and falls over. As she is falling he pulls the tissue paper out which hangs like streamers from his hands to elbows. After a quick shot to show her on the bed, there is a shot of Pinto now holding the tissue in little tiny balls in each hand.

Continuity: In the scene where Otter and Boon are hitting golf balls near the ROTC drills, Otter puts down the golf bag he is carrying and draws a club. The camera moves to the ROTC trainees, and when it comes back to the golfers, the bag is back on Otter's shoulder and there is no club out of the bag.

Visible crew/equipment: In the scene just prior to the food fight, as John Belushi goes through the cafeteria line putting the food on his tray (which moves frequently), note the cameraman's feet in the mirror over the food following him.

Other: In the scene where the Mayor is giving his speech just before the parade begins, there is a man sitting in the bleachers behind him making bizarre faces and hilarious facial ticks in plain view of the camera.

Continuity: When the Fraternity house is being taken down, the Greek letters switch places.
