Quite possibly the coolest TV show ever created (for geeks) is How It's Made.  I always think I won't be interested in learning how pet food or aluminum baseball bats are made, but I'm always wrong.  I'll see the show listing as I flip through channels and think, "Meh, I don't feel like learning right now."  But even before that thought finishes jumping across my neurons, I'm immersed in the show and can't look away.  Who knew the manufacture of yogurt and candles was so involved and so awesome? #entertainment
