Katherine Hepburn and the Devil's Lettuce

Apparently, Katherine Hepburn used to smoke a lot of Marijuana.
During the shooting of "Little Women" in 1933, she and Douglas Montgomery got so Rasta that they drove a horseless buggy into a crowd in Dover, Massachusetts and knocked a cooper right out of his spats.
Montgomery went on to fame as the first caulkasian man to use the word "beeyach".
