Variety reported Furst died in his Moorpark, Calif., home on Friday.
"Steve has a long list of earthly accomplishments. He was known to the world as an brilliant and prolific actor and filmmaker, but to his family and many dear friends he was also a beloved husband, father and kind friend whose memory will always be a blessing," Furst's sons Nathan and Griffith wrote in a Facebook post Saturday.
"To truly honor him, do not cry for the loss of Stephen Furst. But rather, enjoy memories of all the times he made you snicker, laugh, or even snort to your own embarrassment. He intensely believed that laughter is the best therapy, and he would want us to practice that now."
"If you knew him personally, remember his gift for lighting up a room. And no matter who you are, when you think of Steve, instead of being sad, celebrate his life by watching one of his movies or use one of his bits to make someone else laugh -- really, really hard."
