Help me make a list of people who have been imitated by a President of the United States.

The previous post has video of Harry Truman doing an imitation of the radio commentator H.V. Kaltenborn. And I can remember Barack Obama imitating Al Green. Or maybe that shouldn't count. He was just doing his best at singing "Let's Stay Together." Oh, I see that later he joked: "Tonight, I am speaking not just as a President, but as one of America's best-known Al Green impersonators." Obama also imitated the Seahawks' Richard Sherman: "I'm the best President in the game!"

I couldn't think of anything else. I googled people who have been imitated by presidents, and the first hit was a NYT pieced called "The Spirit of the President. Let it be Imitated." which I misread as promising for my list-making purpose. Turned out it was from November 12, 1864. Abraham Lincoln had called upon "all having a common interest [to] reunite in a common effort to save our common country," and the NYT editors recommended an imitation of his "forbearing and generous spirit." That's an immensely interesting detour, profound when I'm being lightweight. I'm only mentioning it because it's my way to blog about the process of blogging, and today, especially, has been a day of blogging details.

I'm genuinely trying to make a a list of people who have been imitated by a President of the United States.
