What does a superstar rapper who has a new book out talk to radio shock jock Howard Stern about: prison fights, of course.

The 31-year-old rapper is in New York on a promo tour for his book: Power & Beauty: A Love Story of Life on the Streets, which was released today. His first stop was the Howard Stern show, where he discussed one of the fisticuffs he had with a disrespectful inmate at Forest City Correctional facility in Arkansas.

Howard Stern: “Where did your fight go down?”
T.I.: “The bathroom.”

Howard Stern: “And, like, a whole bunch of brothers standing around watching the fight? Puttin’ money down on it and everything?”
T.I.: “Yeah. Guys from this side, guys from that side.”

T.I. tweeted his itinerary on his official Twitter.com account yesterday.
