No, I think that is actually Ben Schultz, aka Leeroy Jenkins. I'm doing some research right now...

There are a few Leeroy Jenkins vids on the Sift, but I had no idea what they were about until checking the Wikipedia entry.

Here's the quick summary: "Leeroy Jenkins , sometimes mis-spelled Leroy Jenkins and often elongated with numerous additional letters, is an Internet phenomenon named for a character created by player Ben Schulz in Blizzard Entertainment's popular MMORPG World of Warcraft. The character has become popular thanks to a machinima video of the game that circulated around the Internet. The phenomenon has since spread well beyond the boundaries of the gaming community into other online and mainstream media.

The video was recreated using the recorded audio of the actual event. The video takes place in the Upper Blackrock Spire dungeon in World of Warcraft, inside the Rookery room, one of the most notoriously difficult sections for newcomers to the game.[1] It opens with the guild members discussing an impending raid via audio teleconferencing, complete with regimented battle plan and statistical breakdown of their survival. The fastidiousness of their preparations is ruined by the sudden and unexpected actions of Leeroy Jenkins who was away from his computer. After missing the entire conversation, Leeroy runs into the area without pause, yelling "Alright time's up. Let's do this! LEEEEEEROOOYYYJENNKINNSS!!" There is about a second of stunned silence from his companions, followed by carnage when they proceed to hastily attempt the attack (as Leeroy's actions had now activated nearby monsters). The attempted raid (and video) is filled with desperate calls from the team to mount their original plan, and with insults at Leeroy, even with Leeroy calling "It's not my fault". It ends disastrously, with all the guild members lying dead on the floor, screaming at Leeroy for his brash decision. At the end of the video you hear At Least I have Chicken -- a seeming insult by poor leeroy to make his actions seem validated."

Jeopardy included Jenkins in a clue, but none of the players correctly identified the game when that clue ran.

*nsfw, the *geek *history *videogames *wtf video. Awesome.

I was going to downvote this until I read the Wikipedia entry about Leeroy.

It makes this retroactively hilarious.

Leeroy Jenkins is funny in the right context.

About as funny as Leeroy Jenkins, which wasn't.

Hey, isn't that the room from the Leeroy Jenkins video?
