Enjoy a classic Smart Drivel episode as Jon and Kurt set out to find the truth behind certain “givens” that we have always been told: is it safe to swim right after eating? Is the earth round? Did Vikings have horns on their helmets? Was there an apple in the Garden of Eden? Were the pyramids of Egypt built by slaves? Is Everest the tallest mountain on earth? And what the hell does Chuck Yeager have to do with all of this?
