Which reminds me of my favorite Don Rickles story which he told many times on talk shows about his friend Frank Sinatra. I'm approximating it from memory, but this is pretty close to the way he tells it:
I’m with a date in Las Vegas in the early 60’s. I’m out with this girl, and we’ve brought her parents with us to a fancy restaurant. I see Frank Sinatra on the other side of the restaurant. Everyone’s buzzing with excitement. I get up to go to the bathroom and sneak over to where Frank’s sitting. I say to him, "Hey, Frank, I’m on a date with this girl I really like and her parents are with us too. I hate to ask you this, but it would really be great, and it would really impress them, if you’d just come over and say hello for a minute."
He says, "Of course, Don, anything."
"Gosh, I sure appreciate it, Frank. You're the best," I tell him.
I go back and sit down and we’re eating and I’m telling her parents a story, and a here comes Frank over to say hello. He walks up to the table and says, "Hey, Don, how ya doin'?"
I stop in the middle of my story, turn to him, and say, "Geez, Frank, not now! Can’t you see I’m with people?"
