Leeroy Jenkins and his bizarre battle cry

This bizarre video comes from those obsessive World of Warcraft players. It is an oldie, but a goodie. In the video, a group of gamers carefully plans a raid. That is not bizarre. What is bizarre is that Leeroy Jenkins humorously and unwittingly botches the raid for all of the hardcore gamers with him. He then goes on to become famous for it. Yes, seriously. He even has his own Wikipedia page.
