William recently made an appearance in the American Ninja Warrior competition. The episode was aired on G4 last night, and apparently, he made it to the devil stairs before he fell. Check out 3 preview screen shots in the gallery, thanks to Michelle. We’ll let you guys know when the video is available online!
EDIT: With special thanks to Mo, you can check out the video below. High quality screen shots have also been added to the gallery. Enjoy!
