This World of Warcraft parody is a bit old but still remains hilarious and is entitled the World of World of Warcraft. This comedy video imagines an online video game, where a user can play as a World of Warcraft user. Huh? Who? What do you mean? Just watch the video.
Basically, it pokes fun at World of Warcraft players and obsession. You get to play someone who is playing the video game. Instead of needing to press a certain button to make a WoW character do something, you will in fact select an action that will make your character select that action. I think I just confused myself, so as I mentioned, you should just watch the funny WoW parody video from the Onion.
Thanks Oded for the link.
