Bill Murray was a pre-med student until he got busted for pot on his 20th birthday, and it changed his life forever. While waiting to board a plane in Chicago on September 21, 1970, he jokingly told another passenger he had bombs in his bag. A ticket agent overheard him, US Marshals searched his luggage and found $20k worth (10 lbs) of weed, he was put on 5 years probation, and, in a flash, his college career was over… so he became an actor instead.

James Earl Jones once traveled across the United States and used his legendary Darth Vader voice to talk to truck drivers on his CB radio… but it freaked them out so much, he had to stop doing it. ()
