Calvin Coolidge was a former USA Vice President and President. He was vice president until the current President at the time, Warren Harding, died, so he suddenly became the President. After that, he got an elected term. He was also notably silent, to the point where he was nicknamed "Silent Cal". For example, a lady once betted him to say more than three words at a specific point during his presidency. He responded with "You lose.".
In his first animutation apperance, Chickah Jam, he was seen as the foward and backward buttons.
