Five Minute Mario!!!
This video is just amazing!!!! The video is of the new world record for beating the original Super Mario Brothers. There is some argument about if this was a legit win. Because in the video the guy uses game glitches to advance though the levels (wall jumps, and walking through walls.) Which is against some rules of speed playing. If it is or not, this is still a amazing video. Joystiq has a lot more on this so check the source for more on this.
