The Leeroy Jenkins video is a ''VideoGame/WorldOfWarcraft'' video that was made in 2005 and posted in the ''[=WoW=]'' forum in a thread titled "UBRS (vid) ROOKERY OVERPOWERED! blue please," which jokingly presented the video in a serious context. It has since become an Internet phenomenon that has become a part of [[Wiki/TVTropes This Very Wiki]] in the form of a [[LeeroyJenkins trope named in his honor]]. The video is a staged one, though the creators from the guild "PALS FOR LIFE" maintain that [[BasedOnATrueStory it was based on an actual incident]].

In this video, a "PALS FOR LIFE" raid group is making plans for clearing out the Rookery area of the Upper Blackrock Spire, a ten-player raid instance in the Blackrock Mountain zone (the players are speaking to each other via voice over Internet). The area in question contains a large number of eggs being watched over by dragonspawn; if one gets too close to the eggs, they will hatch into baby dragons called Rookery Whelps, and if too many of them spawn, they can quickly overwhelm a group, which is why careful planning is needed to take the room on. The main reason the group are at the Rookery is because Leeroy, one of the two paladins of the group, needs a Devout Mantle, a piece of cloth armor that the others say will help him heal better, off Solakar Flamewreath, the Rookery's main boss.

As the group are making their plans to take on the boss, Leeroy's player is away from his keyboard heating up some fried chicken. The plan that they come up with involves gathering all the whelps into one spot so the mages (Ritter, Spiffy and Therien) can blast them all down with their Area of Effect attacks, while the warriors (Anfrony, Basphemy and Jamaal) use their shout skills to scatter them so that they don't have to fight too many of them at once, and the paladins (Chrisym and Leeroy) use their Divine Intervention ability on the mages to protect them while they AOE. The group then asks Abduhl, one of the two rogues of the party, for a "number crunch," and [[IfMyCalculationsAreCorrect he comes up with a "32.33 (repeating of course)" percentage of survival]]. To which the raid leader replies, [[ILikeThoseOdds "Okay, that's a lot better than we usually do."]]

It is at this point that Leeroy returns. With no knowledge or regard to the plan that his group has just made and ready to kick ass, he charges blindly and solo into the Rookery with his now-famous warcry of '''''"LEEROY JENKINS!"''''' The group are at first a little stunned at Leeroy's move, but quickly rush in to save their errant comrade with a cry of "Stick to the plan!" But by this time, Leeroy has managed to draw aggro from nearly every mob in the room, and the party is quickly overwhelmed. Leeroy and Chrisym use Divine Intervention on two of the mages, Spiffy and Therien, who soon find that they cannot use their crowd-clearing Area of Effect spells or other abilities because Divine Intervention won't let them ("I don't think you can cast with that shit on!"). Meanwhile, everyone else is dealing with the eggs respawning and dumping even more whelps upon them, and it isn't long before people start dying. Jamaal, the first to die to the whelps, is the first to blame Leeroy for what's happening ("God damn it, Leeroy!"), and this is quickly echoed by the others as Leeroy cries, "It's not my fault!"

As the last party member falls, everyone notices that their Soulstone buffs have expired, preventing them from resurrecting and rejoining the instance. As the video draws to a close, Abduhl says, "Leeroy, you are just stupid as hell." Leeroy's response has become a CatchPhrase in itself: "... At least I have chicken."

!!This video provides examples of:
* AluminumChristmasTrees: At this point in ''[=WoW=]''[='s=] history, it was downright ''common'' for healers, no matter their class, to wear cloth pieces. It's less common now because of in-game bonuses given to players who wear pieces of ''only'' their "preferred" armor class, as well as better itemization.
* AscendedMeme: See the LeeroyJenkins page for details.
* AttackAttackAttack: Leeroy jumps in sword swinging.
** AttackAttackRetreatRetreat: Look closely and you can see him making a break for the door.
* BattleCry: "LEEROY JENKINS!"
* TheBerserker: Leeroy, again, for charging in without a thought.
* {{Catch Phrase}}s: "LEEROY JENKINS!" and "At least I have chicken."
* ComplexityAddiction: The guild as a whole appears to prefer making battle plans that are more complicated than necessary.
* CriticalResearchFailure: Invoked. [[TheTeam The team's]] "plan" involves shielding their mages with Divine Intervention while they cast crowd-clearing AOE spells on the whelps. The main problem with this is that Divine Intervention sacrifices the paladin who casts it (putting a character who can tank and heal out of the fight), and is utterly counterproductive when used on a mage, as whoever is shielded by the ability cannot cast spells or use special abilities. In addition, the other part of ThePlan (involving fear rotation on the part of the warriors) isn't very useful in the Rookery due to the respawning eggs, only keeping the whelps off them for a few seconds before dumping even more of them onto the party.
* FailureIsTheOnlyOption: As noted above, the party was doomed by their own plan, even before Leeroy got everyone killed.
* HilarityEnsues: The result of Leeroy running into the Rookery.
* IfMyCalculationsAreCorrect: Spoofed with Abduhl's number crunch, which has no real math to back it up.
* ILikeThoseOdds: Jamaal, after being told the party's chances of survival. He notes that the odds are better than usual, which says a lot considering that Abduhl estimated (at best) a 32.33% chance of survival.
* IncomingHam: The moment Leeroy cuts into Jamaal's speech, you ''know'' something's about to go down.
-->'''Leeroy Jenkins''': "All right chums, I'm back! Let's do this!"
* '''LeeroyJenkins''': The {{Trope Namer|s}}... and [[Pantheon/PhilosophyIntermediateGods Destroyer of Philosophies]]!!
* LargeHam: LEEROY JENKINS!!!!!
* LudicrousPrecision: Abduhl's "number crunch," cites a "32.33 repeating" chance of surviving the Rookery run.
* NeverMyFault: Those who blame Leeroy for the whole thing see his cry of "It's not my fault!" as this.
** On the other side of the coin, the raid leader repeatedly chastises Leeroy and blames the entire mess on him, even though the plan ''he'' came up was doomed from the start.
* OhCrap: "Stick to the plan, chums, stick to the--!" The heavy breathing sound on the mic that follows comes off like a RecordNeedleScratch.
* ThePaladin: Leeroy and Chrisym are in this class; warriors who can cast Divine Intervention.
* ThePlan: The first half of the video is PALS FOR LIFE describing their intricate plan for dealing with the eggs of the Rookery; a session which Leeroy is absent from and cares nothing about.
* SayMyName: Come on everybody: '''''LEEROOOOY JEEENNNKIIINS!'''''
* SenselessSacrifice[=/=]StupidSacrifice: Leeroy's and Chrisym's use of Divine Intervention is both stupid and senseless for reasons outlined in the above Research Failure.
* ASimplePlan: Part of the point and humor of the video is that PALS FOR LIFE's plan is too complicated and too stupid to work.
* SpannerInTheWorks: Leeroy ruins the guild's carefully made plan by running in with his famous battle cry.
* StupidStatementDanceMix: [[http://www.youtube.com/watch?v=-N6sqdrJzVo Of course.]]
* TheTeam: PALS FOR LIFE is a ten player raiding party.
* ThisIsGonnaSuck: (''{{beat}}'') "Oh my God, he just ran in." "Shit! ''Save him! Save him!''" [[FromBadToWorse Things snowballed from there.]]
* TotalPartyKill: The whelps and other mobs killed everyone except Leeroy Jenkins himself. He managed to "kite" the whelps into his team and slip out the door, but [[SenselessSacrifice returned to cast]] [[HeroicSacrifice Divine Intervention]]. Spiffy and Therien, shielded by Leeroy's and Chrisym's Divine Intervention spells, [[SoleSurvivor were the true survivors.]]
* UnbuiltTrope: Leeroy may have hastened their defeat, but if they had followed ThePlan as stated they would have lost anyway.
