On Guard

All hail the Pawn Stars when they check out a uniform from the King of England's royal guard. Used by those guarding the royal palace in England since the 1700s, can the guys get the seller to crack a smile, or is he strictly business? Then, Rick checks out a guitar made from a tortoise shell. Does a slow and steady negotiation win this rare piece, or will the price leave Rick shell shocked? And later, when a seller brings in an antique BBQ built in the shape of a pig, the Old Man reminisces about the good old days smoking pork in the South.
