Things get explosive when the Pawn Stars test out an important piece of history. But first, Corey drills down on the chance to buy a vintage dentist's chair. Can he pull out an offer before the seller brushes him off? Next, when an Andy Warhol Superman poster flies into the shop, will the Pawn Stars save the day, or will this work of art be their kryptonite? Then, Corey takes a shot at some miniature toy pistols, while Rick and Chum take a 1964 Cadillac Coupe DeVille for a spin. And finally, when a NASA Training Vehicle Rocket Engine crosses the counter, Rick shoots for the moon to get his hands on an out-of-this-world item.
