American comedy has as distinct and varied a voice as America itself -- which should be no surprise, considering how vast our comedians' backgrounds are. Although it may seem like the most powerful comedic voices in the United States are concentrated in geographic clusters, the truth is that some of the most enduring personalities are represented all across the country. Some use their birthplace is part of their identity (like Jeff Foxworthy, born in Atlanta, GA), while others are more surprising. (Who knew Steve Martin is a hometown hero of Waco, TX?)
