Sam Simon’s name has been in The Simpson’s credits as executive producer since 1993. It was a savvy business move on his part, which kept the money from the series he created with Matt Groening coming in. His take for doing nothing each year? Ten million dollars. So for 20 years he has made $10 million per year.

Simon married Jennifer Tilly, for a while. Then he married Playboy Playmate Jami Ferrell. But marriages ended in divorce with no children. Now Simon has a ton of money and no one to inherit it.

And now Simon is dying. Five months ago Simon was diagnosed with terminal colon cancer. He was given three to six months to live and vowed that he would give away all of his Simpson’s royalties fortune.

Simon not only wrote the Simpson’s gags. He wrote for loads of other shows including Cheers, Barney Miller, Taxi, It’s Garry Shandling’s Show, and Fat Albert and the Cosby Kids.

Ex-wife Jennifer Tilly said about Simon, “I think it’s really nice for him that he’s doing it now and he gets to see the results of his philanthropy. He really does have a passion to survive, and the longer he’s on the earth, the more good work he can do.”

Simon told the Hollywood Reporter that he enjoys giving away all his money. “The truth is,” Simon says, “I have more money than I’m interested in spending. Everyone in my family is taken care of. And I enjoy this.”

Simon has a particular soft spot for animal causes, especially PETA.

“I want medical experiments on animals stopped,” he says. ‘They don’t do anything, and they don’t work. Veganism is an answer for almost every problem facing the world in terms of hunger and climate change. It helps people’s health. Meat is the biggest greenhouse gas producer. There’s also the cruelty and suffering aspect.”
