* BrokenBase: Is the show better or worse with Squigglevision and the more obviously unscripted dialog from season 1?
* CrossesTheLineTwice:
** Anytime [=McGuirk=] starts to yell at Melissa for asking questions at the soccer field.
** When [=McGuirk=] was acting as a Big Brother for a LittlestCancerPatient, he tells him he's going to kick the ball hard, and boy does he.
* CrowningMusicOfAwesome: Nearly every piece of music in the show, but particularly "Don't Kill Children" and "Taste The Fame".
** "No Skin Off My Ass" from ''Improving Your Life With Improv.''
** "Don't Put Marbles In Your Nose", "Mr. Pants" and "The Wizard's Baker."
-->''Put them in there/Do not put them in there.''
-->'''Dwayne'': ''I'mAWizardWizardAWizardWizardAWizardMan''!
-->''I'm Mr. Pants and I'm comin' to getcha/Better run for your life, better run or I'll getcha''
** "Taste The Fame" ''was'' performed by TheyMightBeGiants.
*** They also contributed work on the rest of the songs from the "Camp" episode.
** "Watch It Again".
** "[[http://www.youtube.com/watch?v=hpzjLtzuk1I&feature=related I'll Race]]"
** He. Is. [[Creator/FranzKafka Franz. Kafka!]] [[http://www.youtube.com/watch?v=8uaaF83eVig Franz Kafka!]]
** The entirety of the Franz Kafka rock opera.
** FREAKY! OUTY! FREAKY! OUTY! WOO WOO! WOO WOO!
** Dwayne's guitar solo at the end of Guitarmageddon.
** The "[[https://www.youtube.com/watch?v=RHDpw1V8c_w Septopus]]" theme from ''The Heart Smashers''.
* CultClassic: A small one, but still a cult classic.
* EnsembleDarkhorse: Coach [=McGuirk=]
* GrowingTheBeard: Not that it was bad even when it was cancelled on UPN (though some viewers were put off by the Squigglevision and the overlapping dialogue...and the fact that UPN [[ScrewedByTheNetwork screwed it out of letting it play for more than one season]]), but it really came into its own on Creator/AdultSwim.
* FoeYay: There's some between Shannon and Brendon, most notably in the episode 'Bye Bye Greasy.' Shannon breaks into Brendon's room, comments on all his clothing on the floor, then this beauty happens.
-->'''Shannon:''' (grabs Brendon by the shoulders) ''I wanna sing, I wanna dance, let's make this happen!!'' (holds him.)
-->'''Brendon:''' ''W-Why are you putting your..arms on me?''
** Fenton also tends to get a bit over-touchy and protective of his 'Bren-Bren.'
* HilariousInHindsight: The end riff of the "Starboy & The Captain of Outer Space" theme song was later re-used for the ''WesternAnimation/{{Metalocalypse}}'' theme song.
** Another ''Metalocalypse'' one: In "Temporary Blindness", Tucoo Von Laserstein sounds a bit like a prototype of Skwisgaar Skwigelf.
* SeasonalRot: Season 4 was considered as this while it was still airing.
* TastesLikeDiabetes: Walter and Perry's codependent relationship produces the most sickeningly sweet dialogue in any given episode.
* ToyShip: Jason apparently has plans to marry Melissa.
** Apparently? He has an entire elaborate proposal set up, although ask him and he denies it.
** There's also Brendon's brief relationship with Lani in "Yoko"
* TheWoobie: Melissa is often this when she interacts with [=McGuirk=]. Especially in the mall scene during "Shore Leave".
