Continuity: At the least swim meet, Chaz is shown diving before Jason Melon. Howver, after Jason dives, it then shows Chaz "up next" - and his hair is completely dry.

Continuity: The college, Great Lakes University, is presumably pretty far north and the movie takes place in January. All of the characters are dressed appropriately in winter coats, except for in the diving scenes, where it's warm, sunny, and perfect for getting a tan.

Revealing: When Thornton and Lou are making the Bruce Springsteen sign, the student at the table is supposed to be writing on a poster but you can see that the marker is not touching the paper.

Other: After his wife has a party at their house, Thorton Melon (Dangerfield) decides to have a swim in his pool. The camera shows Melon as he is about to dive into the pool from the edge. The camera cuts away and a much "thinner" Melon is seen doing a flip into the water. Watch carefully as the "thinner" man makes his dive. You can clearly see his hairpiece fly off the top of his head.

Continuity: During the fight scene in the bar, after the pep-rally, Lou (Burt Young) is seen pressing a guy over his head. The guy is wearing a denim vest, with a red sweater on underneath. After Lou throws the guy's head into the jukebox, the guy who is sticking out of the jukebox is wearing a full denim jacket. The red sweater and vest disappear.

Continuity: When Thornton invites the two girls to sit down and have some beer, the girl with the long hair sits in the middle of the booth but when the shot changes, she is now much closer to Lou.

Visible crew/equipment: When Philip and Diane are walking to the car discussing their relationship, you can see the boom mic reflected off the black car next to Philip's car.

Other: Rodney Dangerfield dives into the pool to show his son a dive. When he climbs out, he's bone dry!
