Without question, stoner humour begins with Cheech & Chong’s debut. They’re absolute masters of grass jokes, yes, but it’s their gift for richly detailed scenes buzzing with little absurdities that makes them such game-changers. One of their best skits, “Dave”, is a knock-knock joke ingeniously spun into a screwball comedy of errors between a paranoid dope dealer and his way-too-high customer. Even nuttier is “Trippin’ In Court”, a long and winding sketch about a mumbling, self-righteous hippie and his shifty lawyer.
