American on Purpose is a moving and achingly funny memoir by Craig Ferguson, detailing his journey of living the American dream. From the mean streets of Glasgow, Scotland, to the comedic promised land of Hollywood, Ferguson's story is one of resilience and humor.

Along the way, he stumbles through several attempts to make his mark—as a punk rock musician, a construction worker, a bouncer, and, tragically, a modern dancer. To numb the pain of failure, Ferguson found comfort in drugs and alcohol, addictions that eventually led to an aborted suicide attempt. (He forgot to do it when someone offered him a glass of sherry.)

But his story has a happy ending: in 1993, the washed-up Ferguson washed up in the United States. Finally sober, Ferguson landed a breakthrough part on the hit sitcom The Drew Carey Show, a success that eventually led to his role as the host of CBS's The Late Late Show. By far Ferguson's greatest triumph was his decision to become a U.S. citizen, a milestone he achieved in early 2008.

In American on Purpose, Craig Ferguson talks a red, white, and blue streak about everything our Founding Fathers feared.
