When I was a kid and I was on Set while he and my dad were doing whole nine and whole 10 yards he was so kind and funny and sweet with my sisters and me and I think his physical Comedy and that movie still makes me laugh so much."
She added, "I know he had many challenges in his life and brought a lot of joy to people with his comedy. I hope he can rest peacefully."
