Then you've obviously never heard the song...that apparently everyone has heard and accepts as law...not quite sure WHY, but some stoned reggae dudes pretty much created a law in the stoner culture by writing a song that says "pass the dutchie to the left hand side"
the slow mo game.. you get 2 people, one pretends to throw an invisable baseball at the other person's face. the other person has to react realistically (they HAVE to get hit in the face, you cant dodge it), but really, really, really, really, really, really, really slow. the slower the better. its fun when you're sober too.
