Pawn Stars: Rick vs. the Globe of Death

Rick and Chum get a relatively genius package containing letters signed by Albert Einstein. But can they figure out the equation to work out a deal? Then, Chum and Corey marvel at replicas of Thor's helmet and hammer. Will they nail the negotiation, or be deemed unworthy? Next an antique game shuffles into the shop. Will Corey try to bet the house, or will he strike out? And finally, Rick heads out to meet Spencer for a death-defying picking adventure of global proportions.
