Johnny Carson has had a lot of people on his show.

Many people will never forget when Don Rickles and Frank Sinatra were on an episode in the 1970s. Don is now 90, but when he was on Johnny’s show, he performed a bit of his comedy routine that left the audience in stitches.

While on the show, Don made a few remarks about Frank’s Italian family history. He made these remarks when the mob was still very active and played a large part in the society of the United States. Some wonder how he made it through the show with those comments.

Rumors swirled that Frank was active with the mob. The Johnny Fontane character in the movie “The Godfather” is said to be based on Frank himself.

Don and Frank talk on the stage about their careers and some of the challenges that they faced as well as their successes. The audience begins laughing when Don jokes about Frank and the mob.

Don sends messages from some of the people involved in the mob. Frank laughs throughout the entire bit, but you can tell at some points that he becomes irritated with the talk about the mob and the people involved.
