can i just echo The Big Lebowski and Fear and Loathing
I watched the first with my brother/step brother stoned as hell on vacation in Florida, and i'm reading the book of the second and its just so good
also gotta suggest the Scooby Doo live action movie, i know its terribad but a friend pointed out there's a lot of hilarious pot references (Shaggy meets a girl named Mary Jane, for example. quote him: "that's like, my favourite name!")
