* BigLippedAlligatorMoment: The "alternate ending" to the series finale. It consists of an alien invader appearing out of nowhere and the cast attacking him. You may see it here: http://www.teennick.com/videos/clip/alternate-ending-clip.html
* BizarroEpisode: The Halloween special.
* CriticalResearchFailure: Van Earl Wright occasionally referring to Willie Gault as an "Olympic Gold Medalist" whenever the two would show up to commentate on a major happening at Polk. Gault never competed in the ''Summer'' Olympics, though he did go to the 1988 ''Winter'' Olympics in Calgary as a member of the U.S. Bobsled Team, even though he ended up on the sidelines the whole time. The one year that Gault would've been in the Summer Games was 1980, the year the United States, along with many other nations, boycotted the Games, taking place in Moscow, out of protest of the Soviet Union's invasion of Afghanistan. In the days leading up to the Games, Philadelphia staged what was officially known as the Liberty Bell Classic, but is also referred to as the Olympic Boycott Games, as many of those boycotting countries took part. The Classic exclusively consisted of track and field events. Gault won a gold medal in the 4x100 meter relay, and a bronze medal in the 100 meter sprint in a USA sweep of the podium. The gold medal is the one the writing staff mistakenly thought Gault won at an actual Olympics. Gault, though, was a member of the Chicago Bears when they won Super Bowl XX over the New England Patriots.
* EnsembleDarkhorse: Coconut Head. Full stop.
** Gordy also qualifies, as he was elevated from a recurring role in Season 1 to a starring role in Seasons 2 and 3.
* FamilyUnfriendlyAesop: The ''Class Clown'' episode. While it is true that being amusing can lighten the tension in a School Environment, the episode encourage the viewer to clown around, even if it results in you getting in trouble.
* GettingCrapPastTheRadar: Just what did Moze say in the "Bad Habits" episode?
* HilariousInHindsight: iTeacher appeared long before iCarly ever existed.
* HoYay: Between Ned and Cookie.
** Also between Loomer and Cookie.
-->'''Loomer''': Together, Cook, we will rule the dodgeball court!
** Plus Cookie's whole subplot in Guide to: Girls, when Loomer fell in love with Cookie when he was dressed in drag.
-->'''Loomer''': (''grabs "Simone's" hand'') You're special, and I'd like to get to know the ''real'' you.
-->'''Cookie''': (''nervously'') No, you don't!
* HollywoodHomely: Lisa. [[UnnecessaryMakeover Until the third season, that is.]]
* LesYay: Between Moze and Suzie.
* OvershadowedByAwesome: While the show was relatively popular, shows like ''Series/DrakeAndJosh'' and ''Series/{{Zoey101}}'' are more likely to be recognized. It certainly ''was'' more popular than shows like ''Series/{{Unfabulous}}'' or ''Series/JustJordan''.
* SpecialEffectFailure: The show frequently uses puppets and unconvincing PeopleInRubberSuits to portray various animals, and sometimes rather obvious dummies representing characters doing painful stunts. It seems that this is largely done on purpose, considering the cartoony nature of the show to begin with.
** This is actually invoked in one episode where Moze thought she'd knocked out two of Coconut Head's teeth. The "teeth" are obviously pieces of white breath mints that have been cut to resemble teeth. Since audiences were used to the terrible effects, the audience just assumed it was his teeth. Then it was revealed that it really was breath mints in-universe as well.
* SuspiciouslySimilarSong: The first chords of the tune that plays when Ned is explaining his tips to the audience sound a lot like the main riff of "I Can't Explain" by TheWho.
