A tape of Dog the Bounty Hunter star Duane "Dog" Chapman using the N-word in an angry phone conversation with his son Tucker is making the rounds on the Internet. On the call, Chapman is heard using racist remarks during an argument over Tucker's girlfriend, Monique Shinnery, who is black.

Chapman's show, in which he and his family chase down criminal fugitives on the Hawaiian Islands, has been one of the most popular on A&E since it began its run in 2004. - Reporting by Stephen Battaglio
