A U.S. Navy foghorn; a pair of vintage Aerosmith tour shirts.
Go to DEFCON 1 with the Pawn Stars when a seller claims he has a cover for a thermonuclear warhead. Can Rick successfully defuse the negotiation or will it blow up in his face? Then, Corey swings into action when a mandolin from Bob Wills' Texas Playboys comes into the shop. Will he pull some strings for the country classic or will it be out of tune? And later, Chumlee tries to find something he's better at than Rick. Will he be able to beat the boss or will Rick prove once and for all don't mess with the best?
