Photos: Diagnosed with terminal cancer, 'Simpsons' co-creator Sam Simon is giving away his fortune

Diagnosed with terminal cancer two years ago, and given only months to live, Sam Simon is still alive and still racing to spend the fortune he made as co-creator of The Simpsons on causes he loves, whether he is rescuing grizzly bears (and chinchillas and elephants) or funding vegan food banks. As Simon's friends and fellow activists gather for his 59th birthday, another friend, Merrill Markoe, reveals how a force of comedy faces his own tragedy.
