Revealing: At the parade only one or two smoke sticks are shot into the crowds, but when the DeathMobile first emerges through the smoke you can see dozens of billowing smoke sticks aligned across the ground.

Continuity: When they take Flounder's car to go pick up some chicks, Otter puts a can of beer on top of the car. In the next shot the beer is not on the car anymore.

Factual error: Bluto crushes a beer can against his forehead. Steel cans are too strong to crush like that. Aluminium cans weren't introduced until approximately 1965, although the movie was set in 1962. http://www.cancentral.com/brochure/historyTimeline_f.htm.

Continuity: At the parade, Bluto uses the banner to jump to the street. In the next shot the banner is intact again.

Factual error: In the scene where Larry and the Mayor's daughter are on the football field, it appears to be artificial turf. Artificial turf wasn't invented until 1965, 3 years after the movie was to have taken place.

Continuity: In the scene where Bluto is watching the pillow fight through the window, when Mandy comes in the room and the girls stop to talk to her, every time the camera cuts from Bluto to the girls the girls have changed positions in the room.

Factual error: Listen to the crickets chriping at the football field where Larry and the Mayor's daughter make out. It's fall, everyone has jackets on. It's much too cold for crickets to chirp that rapidly. (Or at all at that time of year).

Factual error: You can see that the Jack Daniels that Bluto chugs is not real, because it foams. It was probably iced tea or something.

Factual error: Mrs. Wormer confuses the meanings of "sensual" and "sensuous". Sensuous merely means appealing to the senses; sensual has sexual connotations. In other words, vegetables are sensuous; people are sensual.

Continuity: When Larry meets Karen Allen's character at the frat house, she offers him a beer.   When you see the back shot of Larry, he is holding the beer glass in his right hand.  When it switches to a frontal view of Larry, he is holding the glass in the left hand.

Continuity: After Stork pushes the drum major off camera to the right and seizes his baton, the scene cuts to a longer shot where he leads the band in the same direction. The drum major has disappeared.
