''Profound Moments in Left 4 Dead 2'' is a comic LetsPlay {{Machinima}} about the videogame ''VideoGame/Left4Dead2''. Four dudes with microphones [[ObfuscatingStupidity allegedly]] attempt their first playthrough, while HilarityEnsues as they manage to make fun of [[AffectionateParody absolutely everything]] they come across in the game. Even more hilarious when one realises that most of the laughs they create come from fooling about [[AttentionDeficitOohShiny objects, fake adverts and many other props]] that have no real impact on ''[=L4D2=]'''s gameplay.

In each season, the gang will do a playthrough of a ''[=L4D2=]'' campaign. Currently 5 seasons have been uploaded to Website/YouTube. The original cast consists of [[PsychopathicManchild Aovnick]], [[CloudCuckooLander Archaon]], [[DeadpanSnarker PuppySky]], and [[OnlySaneMan Djy1991]] (aka [[AerithAndBob David]]), who is better known as the uploader of the graphic adaptations of some of squirrelking's and Creator/PeterChimaera's works, like ''FanFic/HalfLifeFullLifeConsequences'' and ''FanFic/QuarterLifeHalfwayToDestruction''. In season 2, Archaon was replaced with another player named [[ReplacementScrappy TicTac]], allegedly because Archaon's [[PutOnABus mom had a book club or something]]. In Season 3, two new members, [[ThoseTwoGuys Mastermind and Bro]], replace [=PuppySky=] and Archaon/[=TicTac=]. Season 4 sees the return of [=PuppySky=], in place of Aovnick. Season 5 is a bit of a change, seeing the cast take on the first campaign of the original ''Left 4 Dead''. Mastermind and Bro have been replaced by two entirely new players, [=PsychoDuck=] and Abby Ratso Lee, as well as the surprise appearance of Aovnick taking the place of the helicopter pilot.

See also the Website/SomethingAwful [=LPs=] of [[http://lparchive.org/Left-4-Dead/ L4D 1]] [[http://lparchive.org/Left-4-Dead-2/ and 2]] by baldurk & co., which are similar in concept, but with a more static cast, slightly less screwing around, and videos of fan-made campaigns alongside official ones.

Perhaps an unofficial continuation of the series is the Amazing Left 4 [=DeAdventure=] by Psychoduck, where he and some friends (including Abby and some of the Icton crew) play through the campaigns from where Profound Moments left off.

!!Provides examples of:
* AerithAndBob: Most of the players are known as their username, but Aovnick is just called Nick and everyone uses Djy1991's real name, David.
* AndZoidberg: [[spoiler:RAMIREEZ!!! Oh, and [=TicTac=] too.]]
* AnachronicOrder: "The Passing", which takes place between "Dead Center" and "Dark Carnival", is played after both. "Swamp Fever" was skipped in favor of "Hard Rain" for the fourth season, and the fifth goes way back to "No Mercy" in the ''first'' game.
* AtomicFBomb: [=PuppySky=], after falling off a speaker in part 9.
* AttentionDeficitOohShiny: All the time, from the very first scene to the end.
** In the Mall Chapter, Archaon says "Whoa, [[DistractedByTheShiny shiny!]]" when he finds a pipebomb. Cue StuffBlowingUp.
** "Hey guys, it's [[MistakenForBadass Gabe Newell]]!"
** "4 dollars for beer!??"
** "Look at the friggin' details on this cup, man!"

** Aovnick also lets one out when Bro pretends to pick Nick just before starting The Passing.
** "OH MY GOD! [[spoiler: BILL]] IS DEAD!"
* {{Beat}}: Every time they get attacked whilst having a conversation, a beat happens before they all start screaming.
** BigLippedAlligatorMoment: The only one who seems to draw attention to it is [[OnlySaneMan David]], otherwise it's never even addressed. Possibly [[JustifiedTrope justified]] in that the other two players, Puppy Sky and Aovnick were being attacked by a Smoker, and then the group was attacked by an [[ItMakesSenseInContext entire army of Jimmy Gibbs Juniors.]]
* BrickJoke: [[spoiler: Archaon at the end of Season 2.]]
** [[spoiler:And then again in Season 3.]]
* BuffySpeak:
--> '''Nick''': Oh you guys and your [[DeathIsCheap fancy closet technology]], so far ahead of my helicopter and its flying... metal things!
* TheCameo: Archaon [[spoiler: shows up in The Port around Bill's body while the rest are screaming. Only problem is, Bro and Mastermind are still there. This leads to [[UpToEleven even more screaming]]. ]]
** Aovnick (and [[CompanionCube Ramirez]], [[TheGhost apparently]]) makes a guest appearance in Season 5 as the helicopter pilot, first announcing that he can't pick the others up in the street because Puppy is too fat (suggesting they head to the hospital to get him liposuction), and then expressing disbelief in [[DeathIsASlapOnTheWrist how many times they all die]] before he can arrive at the roof.
* CampingACrapper: David, Bro, and Mastermind are all checking out some graffiti in a bathroom in ''The Passing'' when a Charger comes in and barrels through all three of them.
* CatchPhrase: "Lovely dinner!"
** "What's going in?"
* CloudCuckooLander: Aovnick
** And Archaon, see WordSalad.
* ClusterFBomb:
-->'''Bro:''' Fucking fuck!\\
'''Mastermind:''' I like to fucking fuck, don't you?\\
'''Bro:''' ...I dunno man, [[SubvertedTrope I kinda like to frickin' fuck...]]
* CompanionCube: Ramirez, the gnome statuette rescued from Dark Carnival.
** And to a lesser degree, Stephanie the chainsaw from later on in the same campaign.

'''Mastermind:''' I don't smoke chains, I smoke cigarettes.

--> "Hello sir do you happen to sell any garden gnomes? ... I SAID do you SELL GARDEN GNOMESAUUUUGH, RAMIREZZZZZZ
** Nick's comment about "Knowing" the whole "Emo eyeliner thing" in episode 11, considering the end of "Profound Moments in Everything."

* DoubleSubversion: Djy1991 is [[RunningGag constantly being attacked by Hunters]]. However, in episode 12, he manages to fend off a Hunter in mid-flight. Unfortunately, [[ButtMonkey he later gets attacked by a Hunter again]].
* DynamicEntry: The Special infected. [[RuleOfFunny For comic relief,]] most of the cast screams in pain as they are pounced.
* FanNickname: David invents the nickname "Gabe Newell" for the Boomer, but Nick uses it the most.
** [=TicTac=] coins the less popular "loan-sharks" for the Common Infected.
* {{Filler}}: The ''Profound Moments in EVERYTHING'' episode which was made while waiting for a vital cast member to return from a trip through the states.
* FirstNameBasis: Djy1991's teammates all call him by his first name, David.
* GenreSavvy: Archaon points out that they shouldn't be playing on [[HarderThanHard Expert]] early in season 1. Bro reiterates this in the third season.
* GunPorn: Subverted when Archaon enters Whitaker's gun store and begins to point out the flaws in the gun models of the game in what appears to be FanDisservice to him.
* HeroicSacrifice: [[spoiler: Ramirez]]
** [[spoiler:[[AndZoidberg And TicTac]].]]
* HypocriticalHumor:
-->'''[[PsychopathicManchild Aovnick:]]''' David, take your pills!
** And also in the first episode, when referring to the helicopter at the start of Dead Center:
-->'''Aovnick:''' WHY IS IT SO '''LOOOOOOOUD?!'''
* ICallItVera: Stephanie the Chainsaw.
* InfernalRetaliation: Not a by-the-book example. [=PuppySky=] attempts to sing, but Aovnick refuses to pipe down. Puppy, being [[{{Jerkass}} the guy]] he is, lobs a molotov.
-->'''[=PuppySky=]:''' FUCK YOOOOU!\\
'''Aovnick:''' Ha ha''AAAAAAAAH, '''AAAAAAAAAAAAAAAAH'''''
** In the same episode, when [[HollywoodToneDeaf Djy1991]] tries to sing the others set ''him'' on fire.
-->'''Djy:''' Baby, baby, baby ''oooohhhh''. Baby, baby, baby ''ooOOOooohhh''. aaa'''''AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHH!!!!'''''
* ItSeemedLikeAGoodIdeaAtTheTime: Balcony jumping, which, [[EstablishingCharacterMoment like just about everything else they attempt afterwards]], results in a TotalPartyKill.
* JustIgnoreIt: In The Passing, Bro and Djy1991 sit in a restaurant booth, concentrate on having a lovely dinner, make small talk, and avoid eye contact with the Tank in the room. Doesn't work.
* LaserGuidedKarma: In Episode 7, [=PuppySky=] picks up Djy1991's defib pack... and promptly revives Aovnick with it. They then walk around the corner and get puked on by a Boomer.
** One of the top reasons the Charger seems to like Puppy.
* LaserGuidedTykebomb: The Chargers, to [=PuppySky=]. To lesser degrees, Hunters to Djy1991 and Tanks to Bro.
-->'''[=PuppySky=]:''' [''Sighs''] [[WhyDidItHaveToBeSnakes Every single time I die is a goddamn Charger]]!
* LostForever: When Ramirez gets stuck in Kiddyland.
* MadnessMantra:
-->'''Bro:''' [''Whispering''] It's okay, he doesn't see us. He doesn't see us. He doesn't see us. [''More zombies appear and Bro starts shouting''] HE DOESN'T SEE US! HE DOESN'T SEE US! HE DOESN'T SEE US!
* MajorInjuryUnderreaction:
-->'''Mastermind:''' Oh, fuck, I'm burning.
* NamesTheSame: [[invoked]] Aovnick, referred to as Nick, playing as Nick.
* NoodleIncident: In Episode 16 of Season 4, Mastermind keeps trying to talk about this one time where [=PuppySky=]'s car broke down. However, whenever he does, [=PuppySky=] immediately screams at the top of his lungs to censor anything Mastermind says.
* NWordPrivileges: "Does this mean I can say the N word without getting in trouble?"[[spoiler: '''"NOOOOO"''']]
* ObfuscatingStupidity: Debatable, but it seems that no one in the cast is actually a total newbie to the game, given Djy1991's background and that no achievements are earned in the first two seasons.
* OhCrap: Djy1991's reaction after being greeted by a Hunter.
--> ''(Bro is puked on by a Boomer)''\\
'''Mastermind:''' Hey Bro. You know what that is on you? That's the Source engine.\\
''(Car alarm goes off)''\\
'''Aovnick''' and '''Djy1991:''' [[OhCrap Oh shit/Oh crap!!!]]
* OffScreenTeleportation: Even [=PuppySky=] doesn't know how he got on top of the Midnight Riders' stage. [[RunningGag As usual, a Charger helps him back down]].
* PutOnABus: Archaon since Season 2. [=PuppySky=] in Season 3, Aovnick in Season 4.
* PsychopathicManchild: Aovnick definitely comes across as one of these.
-->'''Aovnick:''' Dude, a rollercoaster! DUDE, A ROLLERCOASTER! '''OH MY GOD, A ROLLERCOASTER!'''
* RapidFireComedy
* ReactiveContinuousScream: Djy discovers [[spoiler:Bill]]'s dead body in The Passing and starts screaming. Mastermind then belts out his catchprase, Bro walks in and begins screaming as well. [[ScreamingWarrior Aovnick]] stays silent.
** Happens a lot, in fact. Another example is in episode 10, when a Charger knocks over Djy out of nowhere (around 3:52).
* RunningGag: No matter where [=PuppySky=] is, a Charger will find him.
** Not to mention Djy1991 and the Hunter.
** Almost every time Ramirez' name is said in season 2, [[VideoGame/ModernWarfare Sergeant Foley's]] head is overlaid on the screen.
** One teammate keeps shutting the safehouse door at the end, preventing Djy1991 from getting inside. Another teammate then incaps the first , allowing Djy to enter.
--->'''Djy1991''' ''(playing as Rochelle)'': Let me in!\\
'''Archaon:''' No girls allowed.
*** Finally subverted when Djy is the only one who manages to make it into the safe room alive in episode 5, wherein Nick tells him that girls ARE allowed in this one room.
* SchmuckBait:
-->'''Aovnick:''' Hey, there's a bottle [[SuperDrowningSkills in the water]], I think we can get it!\\
'''Bro:''' OKAY!
* ScreamingWarrior: Sweet holy hell, '''''Aovnick'''''.
* ScreamsLikeALittleGirl: Mastermind, when he is attacked by a Boomer.
* ShoutOut: Of all things, to ''Disney/{{Mulan}}''.
-->'''Aovnick:''' ''(singing)'' Let's get down to business--[[DynamicEntry OH GOD]]--
** When David points out how slow the elevator in the mall is.
--->'''Djy1991:''' Is this like ''VideoGame/{{Mass Effect|1}}'' or what?
** [[Film/{{Predator}} "GET TO THE CHOPPA!"]]
** [[VideoGame/ModernWarfare Ramirez]] the garden gnome. "[[ItsUpToYou Ramirez, kill that Tank]]! [[MemeticMutation Ramirez, bring my friend back to life!]]"
** At the end of Season 5, [=PuppySky=] declares he will [[VideoGame/DutyCalls start saying "Boring" every time he fires his weapons]]. After about a minute, this culminates in him saying [[VideoGame/TheLegendOfZeldaCDIGames "Gee, it sure is boring around here"]].
* StuffBlowingUp: About three times more than a normal playthrough.
* TakingYouWithMe: In the first episode, the Charger manages to do this to Djy1991, crashing into him while at the edge of the building, meaning that ''both'' the Charger and Djy1991 died. It ''nearly'' took out Aovnick as well, though he managed to grab the ledge.
* TeamPet: [[CompanionCube Ramirez]] in season 2, to the point where not even [[DeadpanSnarker Puppy]][[JerkAss Sky]] seriously considers leaving him behind. He doesn't physically show up again afterwards, but he is referenced quite often.
* TheReveal:
-->'''Archaon:''' Whoa, I'm a black guy?
* TemptingFate:
-->'''[=PuppySky=]:''' [[PreMortemOneLiner I'm gonna do this entire campaign with 1 HP and beat the shit out of everything with a first aid kit]].
** "Alright, let's stick together this time and not die."
* TotalPartyKill: The group's antics usually result in this, although [[DeathIsASlapOnTheWrist eventually]] they manage to beat every level.
* TheUnintelligible: Archaon makes very strange noises in lieu of speaking sometimes.
* UnusualEuphemism: "FFFFFFFFUTS!" "Get in the futsin' elevator!"
* WhatTheHellHero: Archaon burns his teammates to death in the second episode, because he spent most of the first one dead.
* WordSalad: Archaon engages in one when the team takes the elevator in the mall.
-->'''Archaon:''' I have high respect for this game if you can drive a car...and, [[TheUnintelligible auerh]]...ifyoucandriveacaryoucangojustaboutanywhereyoulikeandyouknow, youcangoanywhereinlifeandbeaverysuccessfulmanandallthatfreshairandexercisewilldoyoualotofgood. 'K, let's go.\\
'''Aovnick:''' What the heck did you just say?
* YouJustHadToSayIt: Djy1991's reply to [=PuppySky=] 5 seconds after he speaks his TemptingFate line.
