Happy birthday to Robin Williams, who turns 63 today (Monday). The comedian and actor rose to fame in the late '70s on the sci-fi sitcom Mork and Mindy and became one of the biggest stand-up comics in the country, thanks largely to his bizarre, cocaine-fueled humor. He later went on to star in dozens of movies -- including PopeyeGood Morning VietnamDead Poets SocietyPatch AdamsMrs. Doubtfire and Good Will Hunting, for which he won an Academy Award.
