I'm bumping this because of its awesome awesomeness.
It IS long (30:08), and besides that, you really need to pay attention. But the rewards are many fold. It is funny, inventive, educational and vastly entertaining.

But do yourself a favor. Remember this thread for when you get home. Lock yourself into your computer room and let the spouse, offspring and pets know not to disturb you for just thirty minutes and eight seconds. It will be worth it.
Well, thirty minutes and eight seconds might not be fair. You will want to watch it again....
