'How High' (2001)
Method Man and Redman go to Harvard ("How did I fail Women's Studies? I love bitches!") after discovering a new kind of chronic that turns them into geniuses. Their secret: using the ashes of their dead friend to fertilize their weed crop.
Stoniest moment: When they run out of their stash, Meth and Red dig up the body of John Quincy Adams and smoke his bones.
