Craig Ferguson stopped by the Late Show with David Letterman on September 25 to promote his new book, American On Purpose: The Improbable Adventures of an Unlikely Patriot.  Originally from Scotland, Craig has penned a memoir of his journey from struggling comedian in Glasgow to the promised land of Hollywood, where he became a US citizen.  Although the book chronicles dark subjects like Ferguson’s battles with addiction and a suicide attempt, it is also hilarious, witty, and inspiring.

I, for one, am glad to count him as a fellow countryman!
