RIP, Don Rickles

Very late to the party on this one. Rickles was hilarious and he had a great run. Some of his best moments were on the old Dean Martin roasts, which are astonishing to see these days -- so many legendary performers -- just look at the people assembled on the dais in this clip, in which Frank Sinatra and everyone within a five-mile radius is a target of Rickles's brilliant shtick. A sample of the master at work:

RIP, Mr. Warmth.
