Grab a ringside seat when the Pawn Stars square off for memorabilia from undefeated boxing champ Rocky Marciano. Can Corey land a knockout blow or will he end up down for the count? Then, Rick checks out a one-of-a-kind, battery-operated, glow-in-the-dark car. Will he take charge and make an electric deal or end up in the dark? And later, Chumlee uses modern technology to ”tele-presence” into work. Can he get the job done or will Rick pull the plug?
