I've had that same thought myself, having been a lego enthusiast for much of my childhood. When I was a young child, I had always wondered, "What if the oceans and rivers were filled with root beer instead of water"?
Interesting, apparently today my world is somewhat consumed by legos. Just got an email from a good friend who is a financial planner. Apparently tomorrow he's got a big benefits presentation to make to the top brass of a Lego factory.
