* FridgeLogic: The words "big" and "little" are never invoked to indicate who is mentoring who within either of the fraternities. It would appear that Greg (or Neidermeyer) is the big to Chip's little, Otter to Flounder and Boon to Pinto.
** How did Boon and Otter get their names? Although, if Bluto has been giving them out the whole time, he quite obviously makes most of them up on the fly.
** Lecturing his class on ''Literature/ParadiseLost'', Mr. Jennings asks if "Milton was trying to tell us that being bad is more fun than being good?" He then immediately [[Literature/TheBible bites into an apple]]. It's a wonderfully subtextual gag.
** On the road trip Otter stops by the women's college to score dates for himself and Boon, Pinto and Flounder, and bluffs his way in by claiming to be a recently killed girl's "fiance". He guilt-trips the dead girl's roommate into making out with him in the car, where she drops a hint that she and the dead girl were [[GirlsLove more than]] [[LesYay friends]] and that the roommate ''is using Otter'' for "grief sex".
* FridgeHorror: If you pay close attention to the chronology of the movie, the parade at the climax of the movie starts at exactly the same time (to the MINUTE) that President Kennedy is being assassinated in Dallas. Various aspects of the assassination are parodied in the parade floats. Could also file this under GettingCrapPastTheRadar or RefugeInAudacity.
** The exact same time '''a year earlier'''.
