You forgot to mention "brings his katana to meetings" (the sword, not the Suzuki motorcycle).
It's kind of "friend-of-a-friend", but I had a boss who told me about working with a developer who actually did that, I think at a game company in the late 80s.
By any chance was it puts on sunglasses John Romero?
YEAHHH!
Ninja: that guy who's never at his desk and never says anything in meetings.
