96. Lee-ROOOOOOY JENKINS!
Viral Date: May 2005
A World of Warcraft guild, in the midst of meticulously planning a raid ("I'm coming up with a 32.33—repeating, of course—percentage of survival"), gets undermined when Leeroy Jenkins goes rogue. His battle cry + his guild's ensuing flustered devastation = Internets gold. Yes, it's staged, and kinda racist, but does it really matter?
YOU AUGHTA KNOW:
The Jenkins character, created by a drunk guy named Ben Schultz, has become a WoW trading card, a Jeopardy! answer, and a Toyota commercial.
