* AccidentalInnuendo: In [[http://www.penny-arcade.com/comic/2011/05/20/ this]] strip.
---> '''Tycho:''' What's topping? Let's top. [[DoesThisRemindYouOfAnything I want to top.]]
* CrazyAwesome:
** Gabe; [[http://www.penny-arcade.com/comic/2005/08/19/ Tycho calls him the trope name verbatim here]].
** And of course, World of... [[http://www.penny-arcade.com/comic/2006/04/10/i-hope-you-like-text/ Warhammer Online]]... Craft.
* CrossesTheLineTwice: Many of the strips. Probably the best example would be [[http://www.penny-arcade.com/comic/2004/10/11/ the comic where Tycho gets the hiccups]].
* EnsembleDarkhorse:
** Pretty much any character introduced for a one-off joke can be guaranteed to become a fan favorite, leading to many an AscendedExtra. Examples include Div, the Fruit Fucker 5000, Twisp and Catsby (also SpringtimeForHitler) and the Broodax Imperiate.
** SHUT YOUR PIE HOLE![[note]]Charlie's catchphrase[[/note]]
** Tycho's niece, Anne, also known as Annarchy, won a poll by a landslide to determine which character to focus on as an arc during the authors' trip to Comic-Con 2011. Hence, [[http://www.penny-arcade.com/2011/7/15/ Annservice]].
* HarsherInHindsight: Their [[{{Squee}} reaction]] to ''VideoGame/MetroidOtherM's'' initial announcement could be considered this, as general reaction to the finished product was... [[BrokenBase less than satisfactory.]]
** Gabe shooting a death seeking [[SonicTheHedgehog Sonic]] in the head in [[http://www.penny-arcade.com/comic/2014/11/14/a-ring-and-a-prayer "A Ring and a Prayer"]], in light of SonicBoom: Rise of Lyric becoming an unprecedented critical and commercial disaster just days after the comic was posted.
** Tycho appeared in ''VideoGame/PokerNightAtTheInventory'', a crossover between ''VideoGame/SamAndMaxFreelancePolice'', ''VideoGame/TeamFortress2'', ''WebAnimation/HomestarRunner'', and ''Penny Arcade''. Jerry Holkins even wrote some dialogue for it, and this was back when he was a fan of ''Team Fortress 2''. But then, when [=TF2=] became free to play, he has expressed hatred for it.
* HilariousInHindsight:
** [[http://www.penny-arcade.com/comic/2005/08/29/ This strip]], which is now accidentally brilliant because it makes perfect sense that anyone with knowledge of the future at the time it was published wouldn't remember that "Revolution" was the codename for the Wii rather than a huge historical event.
** Compare [[http://www.penny-arcade.com/comic/2002/06/21 this strip]] and [[http://news.bbc.co.uk/1/hi/world/middle_east/6295138.stm this actual news article.]]
--> "We can categorically state that we [the British military] [[SuspiciouslySpecificDenial did not release man-eating badgers]] into the local area."
** And this [[http://www.penny-arcade.com/comic/1999/11/03 infamous strip]], whose mockery of the bogus release date for [[{{Vaporware}} Duke Nukem Forever]] was funny in 1999 when the game was a year and a half late, but only grew more so as the game grew two years, four years, eight years, ''nine years'', only to loop back around to HilariousInHindsight when a demo of the game, now out of development hell, was released at PAX.
** [[http://www.penny-arcade.com/comic/2004/08/23/ This strip]] became a lot funnier when a few years later Tycho actually did miss a portion of PAX due to the birth of his child.
** [[http://www.penny-arcade.com/comic/2006/03/29/ In 2006, they ran a comic]] where Tycho had a dream in which BioWare received the licence to make a ''Franchise/StarWars'' MMO. [[VideoGame/StarWarsTheOldRepublic Five years later...]]
** Seen [[http://penny-arcade.com/comic/2012/03/14 here]], while discussing [[http://www.penny-arcade.com/comic/2008/9/3/ Gabriel's supernatural powers to destroy computers]]
** [[http://penny-arcade.com/comic/1999/12/27 This is so much funnier when you realize how popular/influential Penny Arcade is now.]]
** Consider [[http://penny-arcade.com/comic/2008/08/11 this strip from 2008]] and [[VideoGame/LollipopChainsaw this game from 2012]].
** A long-running RealMenWearPink joke is that Gabe, the more 'manly' of the two, is secretly obsessed with unicorns and ponies. [[WesternAnimation/MyLittlePonyFriendshipIsMagic This ''used'' to be random and surreal...]]
** In 2003, it was just a [[http://penny-arcade.com/comic/2003/01/24/why-the-hell-not joke on video game movie rights]]. In 2014, [[http://www.movieweb.com/tetris-movie-story someone didn't get the joke]] and actual plans for making a Tetris film began.
* HoYay: Whereof most involves Gabe.
** By the authors themselves:
*** [[http://www.penny-arcade.com/comic/2008/2/1/ "Two Bodies In Space"]] (while poking fun at the physics engine in VideoGame/TheForceUnleashed).
*** [[http://penny-arcade.com/comic/2002/05/06/ The two strips]] [[http://www.penny-arcade.com/comic/2002/05/08/ that introduced Gabe's bisexuality]], and, in a {{Callback}} to that, [[http://www.penny-arcade.com/comic/2006/03/29/ "A Blatant Disregard For Canon"]].
*** [[http://www.penny-arcade.com/comic/2010/08/9/ "In Too Deep"]].
*** [[http://www.penny-arcade.com/comic/2006/03/3/ The Macintosh gag]], and Charles' and Gabe's reunion [[http://penny-arcade.com/comic/2012/04/06 a few years later.]]
*** [[http://penny-arcade.com/comic/2012/04/11 The vasectomy-strip.]]
*** The [[http://penny-arcade.com/2014/01/24/valentines-day-pin1 2014 Valentines' pins]] are heavy on the yay, what with the motif being Gabe and Tycho happily sitting together on a park(?) bench, the perspective making it seem as if their hands are touching, with a huge heart in the background.
** From {{Guest Strip}}s:
*** [[Webcomic/HarkAVagrant Kate Beaton]] weighs in [[http://www.penny-arcade.com/comic/2010/04/05 on the matter]].
*** Webcomic/{{xkcd}} [[LampshadeHanging would]] [[SlashFic like]] to [[http://xkcd.com/160/ join in]].
* InternetBackdraft: As widely respected as PA is, its subject matter choices and... let's say "irreverent" approach have produced a few.
** The controversy over [[BlackComedyRape The Sixth Slave]], which turned into a six-month internet war that resulted in boycotts of PAX and death threats from both ends.
** A more insular version came back in 2006, when the guys mocked a webcomic documentary they found silly and pretentious, singling out Cat Garza--who had ''quite'' the fanbase. They came under a small amount of fire from said fanbase.
** Penny Arcade lost a fair amount of readers after Gabe made transphobic comments on Twitter. [[http://penny-arcade.com/2013/06/21/well-that-escalated-quickly He later apologized, admitting that he had been an asshole and been hurtful to an already-marginalized group.]] [[RuleOfCautiousEditingJudgment This may or may not have been satisfactory.]]
* MemeticMutation: [[http://knowyourmeme.com/memes/why-i-am-so-bald WHY I AM SO BALD?!]]
** [[http://www.penny-arcade.com/comic/2006/04/10/i-hope-you-like-text/ ZALGO COMES]]
** Thanks to Paul Christoforo's very public name and shame on the website, his face ([[https://twitter.com/#!/PaulChristoforo taken from his Twitter account]]) quickly got associated with terrible customer service. His horrible emails - both in terms of content and grammar - supplied such memetic gems as 'Son Im 38 I wwebsite as on the internet when you were a sperm in your daddys balls and before it was the internet'.
** In the more traditional sense of a meme, the word "[[http://www.penny-arcade.com/comic/2005/09/12/ bullshot]]".
* {{Squick}}/NauseaFuel:
** [[http://www.penny-arcade.com/comic/2010/06/09/ Steve Jobs punches out some guy's organs]].
** [[http://www.penny-arcade.com/comic/2008/11/03/ Gabe vomiting out of motion sickness from the Mirror's Edge demo]].
** [[http://penny-arcade.com/comic/2006/11/27 "You just found Grandma's man-candy."]]
** [[http://www.penny-arcade.com/comic/2011/05/18/ This close-up shot of Gabe's mouth.]]
** [[http://penny-arcade.com/comic/2012/07/11 Tycho telling Gabe about something he heard in the bathroom.]]
** [[http://www.penny-arcade.com/comic/2006/04/26 The Bump]], particularly the third and fourth panels.
* TheyChangedItNowItSucks: In early 2003, the comic underwent a shift in art style to a somewhat sketchier look. This caused some initial backdraft, if mainly out of the suddenness of the change than anything else. These days, style changes to match the tone are considered the norm.
* [[ViewerSpeciesConfusion Viewer Videodisc Format Confusion]]: Div, the alcoholic UsefulNotes/{{DIVX}} player, is easily mistaken by newcomers who have not yet read the older strips (or have little to no knowledge on a DIVX player) for a UsefulNotes/{{DVD}} player.
** On a similar note, the wombat symbol is thought to be a bear by people who haven't read the older strips either.
