"In the city of Denver, while I was vice-president, a big husky policeman kept following me around until I asked him what he was doing. He said he was guarding my person. I said: "Your labor is in vain. Nobody was ever crazy enough to shoot at a vice-president. If you will go away and find somebody to shoot at me, I'll go down in history as the first vice-president who ever attracted enough attention even to have a crank shoot at him.""
