Here are a few examples:
17. Andrew Johnson - Who says you have to have to go to school in order to be president? I never attended a single day of classes.
20. James A. Garfield - My assassin shot me in the back. The doctors tried to remove the bullet but they could never find it. I died eighty days after I was shot.
27. William Howard Taft - Some people might describe me as... "pleasantly plump." I guess it's true. When I was elected president, I weighed 332 pounds -- that's more than a baby elephant!
