* FridgeBrilliance: Casey sleeping with Cappie in the Pilot, at first it seems to be easy since he's clearly still in love with her, and she doesn't really seem to be the one night stand type. However, as the series progresses you see that Cappie is the person who would be most likely to get to get to Evan, he's unhappy that she did it, but it's the revelation it was Cappie that twists the knife.
* FridgeHorror: One of the episodes mentions CRU playing "State" in football. The show takes place in Ohio. That means they played Ohio State, one of the best teams in college football (even if they did beat Wisconsin). The result wasn't mentioned probably to avoid the downer ending that would have been their team getting soundly demolished by OSU.
* HarsherInHindsight:
** In "Liquid Courage" Casey remarks that the Evan's parents dinner "needs DJ AM fast".
** Cappie and Casey in the pilot since you realise how much she must have been hurt to feel that made them even[[note]]it takes until the finale for Evan to reach a point where he accepts that Casey never had or could love him as much as Cappie, and even then he's not quite okay with it[[/note]]
* HilariousInHindsight:
** Lizzi's plea to her ZBZ sisters to snap instead of clap because clapping is disruptive, after a feminist conference in England took it one step further and asked their ladies to use "[[http://www.express.co.uk/news/uk/566202/NUS-jazz-hands-clapping-anxiety-feminists jazz hands]]" rather than clap.
** In 'All About Beav' Beaver briefly 'discusses' ''{{Series/Glee}}'' with a janitor. Beav's actor, Aaron Hill, guested on the show half a year after Greek ended. It becomes HarsherInHindsight as his character [[spoiler: is a homophobic bully that [[DrivenToSuicide drives to suicide]] Glee recurring character Dave Karofsky]].
* MisaimedFandom: In the "Great Cappie", Lizzi falls squarely into the lampoon target that missed the point of ''Literature/TheGreatGatsby''.
* ReplacementScrappy: Fans would much rather have Jen K as Rusty's girlfriend than Jordan, despite the fact that Jen K was TheMole...
