American on Purpose

American on Purpose: The Improbable Adventures of an Unlikely Patriot is a memoir written by entertainer Craig Ferguson.

The book details various experiences over several decades in Ferguson's life from his days in Scotland through his migration to the United States; the rise of his performing career in the United Kingdom, then Hollywood, and eventual acquisition of US citizenship in early 2008. He tells about his assorted jobs as a musician in a punk rock band, a bouncer, a construction worker, comedian and actor, as well as his struggle with alcoholism and drug abuse, and contemplation of suicide at a low point in his life.

In December 2010 the audiobook version, read by Ferguson, was nominated for a Best Spoken Word Album Grammy.
