1929 New York Times (Jan 3) 3 [said by former NY Gov. Alfred E. Smith]:
When you get these reports that I'm going to take all kinds of jobs; that I'm going to be a baseball player on the Giants; why, I wish you wouldn't come running up here to ask me about them because you'll know there's nothing to all these dope stories.
