I'm certain that not only do Adam and Jamie smoke weed, but Kari, Grant and that other dude do, too. They're totally a bunch of potheads. They make tons of money and all they do is build shit and then blow it up. There is no better career path for a stoner than to build cool things then watch the explosion while making it look scientific and meaningful (and most of the stuff on that show is pretty scientific and meaningful). Long story short, props to the Mythbuster's crew for finding an occupation which is completely fun and profitable. Bravo. I am envious.
