Don fuckin Rickles was my old school savage of choice. Some of his Roasts, holy hell...
Back when Sinatra was a living deity in Vegas, Rickles asked him to stop by and say hello to him in a lounge he was going to be in one night. Introducing your date to famous people so they can schmooze and get impressed is a thing with celebrities, and he thinks this is happening when he spots Don at a table with a woman. He walks up to the table and starts to say hello and before he can finish, Don angrily cuts him off "You again? What the hell do you want? Can't you see I'm busy here?! Piss off!"
One of the few people who could do that kind of thing back then and not wind up in a 55gal drum.
