* BigLippedAlligatorMoment: The duo grabbing hats and canes for a brief (as in ''two seconds'') dance in "The Photo Man".
* CrowningMomentOfHeartwarming: During the Father's Day episode "Dad", Calvin and Dr Brainstorm, after spending most of the episode trying to get away from their dads, eventually recognize that they really care and humor them, ending up having a good time anyway.
** During the TV Movie, "Invasion", Calvin and Hobbes have a nice moment when Hobbes shows concern about Calvin's safety, and the following reassurance is enough for Hobbes to show some backbone for a change.
** Dr. Brainstorm's small speech at the end of "Thunderstorm".
* GeniusBonus: Among the topics discussed and/or mentioned in "Roughin' It" include [[http://en.wikipedia.org/wiki/Squat_lobster squat lobsters]] that perform [[http://en.wikipedia.org/wiki/Chemosynthesis chemosynthesis]], as well as [[http://en.wikipedia.org/wiki/Acromegaly acromegaly.]]
* GrowingTheBeard: Starts out as RougeAnglesOfSatin and {{Plagiarism}}: [[TitleTheAdaptation The Fan Fic]] before finding an identity of its own by Season 2 and ''really'' starts getting better in Season 3 and beyond.
* HilariousInHindsight: You know how Rupert and Earl's GoldfishPoopGang love [[AlienLunch peanut butter milkshakes]]? [[http://m.dennys.com/en/menu/item/810 Well...]]
** Calvin calls HarleyQuinn [[Webcomic/{{Homestuck}} "Hardly Quinn".]]
** Dr. Brainstorm's original design had him with [[FishEyes unfocused]] gold eyes, like a certain [[WesternAnimation/MyLittlePonyFriendshipIsMagic muffin-lover...]]
* MagnumOpus: The fic is perhaps the culmination of the works of Creator/{{Swing 123}} and Creator/{{Garfieldodie}}. Fitting, since it's a ContinuityCavalcade that still manages to be enjoyable without reading the earlier fics.
* {{Narm}}: While "Have You Seen This Tiger?" is intended to be a {{Deconstruction}} of ThePrankster, Season 1's customary terrible grammar gets in the way.
--> '''Socrates:''' [[ThatMakesMeFeelAngry You're making me angry, Calvin.]] And when I get angry, it makes me [[RougeAnglesOfSatin what]] to use my claws[[WantonCrueltyToTheCommonComma ,]] and tear something up!
* NightmareFuel: [[NightmareFuel/CalvinAndHobbesTheSeries See this page.]]
* {{Padding}}: Season 1 had a RunningGag where Hobbes would misinterpret something Calvin said or did, and Calvin would retort. The duo would then argue for a painfully long amount of time about something with no meaning to the plot. This has thankfully been phased out.[[note]]It should be noted that a similar chain of events was a RunningGag in the ''Literature/HankTheCowdog'' series, which the author loves.[[/note]]
* PainfulRhyme: Calvin's love poem from "Insanity is in the Air":
--> "Roses are red, [[ShapedLikeItself violets are violet.]] Just thought I'd mention that, since [[SpongebobSquarepants Spongebob]] isn't violent."
* TearJerker: Hobbes trying to save himself and the rest of the cast after they've been killed. It's set to '"Wake Me Up Inside" as well.
* WhatAnIdiot: Calvin attempts to fix a satellite dish ''when a tornado is coming.''
