The great @DonRickles has passed. He was funniest and sweetest man I ever met. I have no jokes because Don took them all with him.

Don Rickles was a cyclone of funny with a heart of gold. Is God ready for your maniacal wit? Would love to hear what you said on arrival.

Don Rickles regularly ripped Frank Sinatra to his face, a man who had ACTUAL mob ties, and got away with it. A true American hero.

A national treasure is gone. Don Rickles' talent was limitless. To know him was a gift. He kept me laughing during 58-years of friendship.
