Took me a second to understand this :P Or atleast, how I think its meant to be understood. I'm assuming the 'policemen in our heads' are the thoughts that tell us what we're doing is bad?
I guess it could be taken in more than one way. I think the original meaning was about unbridled creativity.
I just realized that Brad from Giant Bomb sounds like a grown up version of Linus. I don't think I'll ever be able to unhear this.
