I'd never heard the term "mission drift" before but I've seen it a lot. Anyway, Mr. Simon funds animal rescue and also has an agency to feed the homeless vegan meals. I don't watch the Simpsons but this guy seems like a great person with a fun perspective. Cancer is getting to be a real bummer. 

He left The Simpsons in 1993. That's twenty years ago!

His contributions include founding the Malibu-based Sam Simon Foundation (worth nearly $23 million as of 2011) that rescues the hungry (humans -- but with vegan foods only) and strays (dogs, of any variety). His other pet charities include PETA, which in February thanked him for his support by naming its Norfolk, Va., headquarters the Sam Simon Center; international nonprofit Save the Children; and the Sea Shepherd Conservation Society, a global marine conservation organization. His contributions led it to name one of the four ships in its fleet of vessels, used to hinder whaling and illegal fishing, the M/Y Simon in 2012. He also turned a Malibu spread into a canine haven that rescues dogs from kill shelters and trains them as companions for the deaf.

Five months ago, the nine-time Emmy winner -- whose post-Simpsons projects have included directing (The Drew Carey Show), hosting (the short-lived poker reality series Sam's Game for Playboy TV) and consulting (currently on FX's Anger Management) -- was diagnosed with terminalcolon cancer. He confirmed during a May 16 WTF With Marc Maron podcast that he was given the prognosis of three to six months to live and that he will donate nearly all of his sizable Simpsons royalties -- which he has said earn him "tens of millions" annually -- to charity. (Simon's marriages to Jennifer Tilly and Playboy Playmate Jami Ferrell were childless, or child-free, depending on your point of view.) "I think it's really nice for him that he's doing it now and he gets to see the results of his philanthropy," says Tilly. "He really does have a passion to survive, and the longer he's on the earth, the more good work he can do." On July 1, Simon spoke frankly to THR about what goes on in the mind of someone who has much to give but not a lot of time to give it.

He has terminal cancer so it's unlikely he will make it to 2014.

So sad.

And inspiring that he's spending his time figuring out where to donate his money.

Man. So unfair. How are we able to diagnose something and yet not treat it? Why don't we have constant body scans? Never mind. Just sad.

Still alive. Still helping animals:
