Linus' idea of Tux:
So when you think "penguin", you should be imagining a slighly overweight penguin, sitting down after having gorged itself, and having just burped. It's sitting there with a beatific smile - the world is a good place to be
when you have just eaten a few gallons of raw fish and you can feel another "burp" coming. Totally not the vibe I'm getting from this...
