I know this is SO original, but I like Linus Torvalds best. I love that he created Linux originally just as his own little project, and now..I'm sure you all know how big it is.

He also created git, basically because he was tired of the version control systems that were already out there. Just "oh this is shit, I'm gonna write my own", and if I remember correctly, within a few weeks he had the first functional version of git.

Plus the man says that he names all his projects after himself, I think that's pretty damn funny.
