* TheArtifact: Leon, who popularity has allowed him to continue staying with Larry long after any story point justifies his existence. After the rest of his family leaves, Leon ignores Larry's hints and continues to freeload off of Larry. Only in one later episode does Larry finally try to get rid of Leon, but his ploy backfires.
* BigLippedAlligatorMoment: Larry in heaven at the end of Season 5.
* CrossesTheLineTwice
* EarWorm: The credits music.
* MarySue: Subverted to hell and back. Larry is a deeply flawed character who people, quite rightfully, cannot stand most of the time. While there are occasions that he is sympathetic, he commits acts which are pretty much inexcusable from any viewpoint (he once nearly let Jeff and Susie's daughter drown because he didn't want to damage his blackberry and deceived his cancer-stricken girlfriend into leaving him).
* MemeticMutation: "Did you see my show? '''It was called the Holocaust!'''"
* NeverLiveItDown: Bill Buckner in-story. 25 years after committing a mistake that cost the Red Sox the World Series, everybody still hates him for it.
* RetroactiveRecognition: In the episode "The Car Pool Lane", Larry buys weed from [[{{Lost}} Hurley]].
* StrawmanHasAPoint: Larry is almost always the object of scorn and derision for his actions and opinions, but a fair bit of the time the audience is meant to sympathize with his refusal to go along with various abritrary and capricious rules of "polite" society, believing that Larry is typically in the 'right'.
