We’ve all seen the stoner classic “Pineapple Express” by now, and for some of those less experienced stoners asking themselves the same question — yes, cross-joints are real and you can roll one too!

But don’t just take advice from some random asshole writer on the internet. None other than the movie’s star himself, Seth Rogen, has provided eager learners with an extensive tutorial on how exactly to roll one of these bad boys.

It should be noted that you need the following items before starting: weed (a lot), a grinder, one small piece of cardboard, a sewing needle and two rolling papers (one big, one small). I’ll let Seth take it away from here.
