One of my favorite documentaries of all time is
The King of Kong: A Fistful of Quarters.
http://www.imdb.com/title/tt0923752/
If you have not seen it, you can probably find it on YouTube. I didn't link it here because although YouTube doesn't seem to have a problem with that, I am pretty sure that it does violate copyright law. As such, I would encourage you to either buy it for yourself or rent it via Netflix if for no other reason that it is a great film and you should support the director.
Anyway, I found myself completely fascinated by the figure of Billy Mitchell, the high score record holder for Donkey Kong. Here is a guy straight out of the motivational speaker circut, complete with the whole "I'm a winnner" attitude, but with a real dark side. He's just a jerk and he is afraid of Steve Weibe, which leads him to engage in almost cartoonish antics to avoid the latter.
Not a long post from me today, but if you have not seen this, you simply must do so.
