Yeah, I normally hate to just flat out double-post things, but I'm far too pleased with this shirt and I would hate for the two of you who aren't currently following Colors Are Overrated to miss out.
But yes, from Neal Stephenson's Snow Crash comes a t-shirt for the most deadly efficient pizza delivery service on the planet: Cosa Nostra Pizza. Best day job for coders and ninjas there is. You can buy it from ThinkGeek here.
And if you don't know what Snow Crash is, then fie upon you. Do go fix that.
