Hank gives you a sneak peek into SciShow - a new YouTube program that just might change the way you look at your planet, your universe, and even yourself.
If you don't subscribe, you're stupid! Or at least, stupider than you'll be if you subscribed and had Hank to help you learn why everything is the way it is. New episodes coming early January 2012!
