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: success on the hit sitcom The Drew Carey Show, and later as the host of CBS's 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.
