Don Rickles is no more...

He was pretty much an unknown until one night in 1957, when Frank Sinatra walked into a club during his act.

“Make yourself at home Frank. Hit somebody.” said Rickles. Sinatra roared — with laughter.

In 1985, when Sinatra was asked to perform at Ronald Reagan’s second Inaugural Ball, he insisted that Rickles accompany him for a comedy routine. Rickles, naturally, did not spare the president (“Am I going too fast for you, Ronnie?” he asked).

Well...he's gone, and it's a damned shame.

R.I.P., Don. You done good.
