I watched this the other night and thought it was a badass documentary as far as entertainment goes. It's crazy shit when you're stoned. A stoned off your ass documentary. http://www.youtube.com/watch?v=Cm3XdC-p8_I
There is also a follow up which I also recommend watching after the fist one mentioned. http://www.youtube.com/watch?v=5YgbzTmQaYM They are both must see documentaries for when stoned.
