Here is a quote from Wikipedia.
"Robert John Burck (born March 19, 1977 in Cincinnati, Ohio), better known as the The Naked Cowboy, is a New York City busker and prominent fixture of Times Square. His routine, consisting of playing guitar wearing nothing but cowboy boots, a hat, and a pair of briefs, has provided him a comfortable living and international notoriety."
