I can't give just one movie... but I can give a favorite "stoner scene"... the scene in Animal House when they are getting high with the Professor... that shit is ridiculous!
not a favorite, but get fucked up and watch momento. it will fuck you up.
fav would be Dazed & Confused.
Most of the cheech and chong movies. watch the Corsican Brothers on Acid, it will blow you away. I thought it was really dumb when I was sober. then I took a hit of acid or two and watched it and saw things I never saw before. very strange. they knew what they were doing.
I agree with you 100% Big Labowski, Half Baked, Pinapple Express, Grandmas Boy, any Cheech and Chong, How High, clerks, Jay and Silent Bob, Tenacious D, and of coarse the Fridays.
any and all cheech and chongs, how high, HALF BAKED, weeds is great... but she fucks so many people... and jay and silent bob were my roll modles growing up, i wanted to be just like jay...
and lets not forget that fuckin episode of dinosaurs were everyone becomes a stoner cuz they find this "happy plant" in the forest and everyone starts eating it and becoming happy... but then nobody works....
