Revisit the biggest and most expensive items the Pawn Stars have ever seen: a million dollar car crushing machine dubbed "Robosaurus," a cigar box owned by John F. Kennedy himself, a piece of sunken treasure, and a rare Jimi Hendrix guitar that leaves Rick in a "purple haze."

Come to attention with the Pawn Stars when a nightstick believed to be owned by Ulysses S. Grant gets presented to the shop. Will this piece of military memorabilia be a hit or will Rick break off the deal? Then, Corey and Chum roll in to check out a collection of vintage skateboard stickers. Will the guys get stuck on the price or will they do a 180? And later, Chumlee tries to prove to Rick he is a multitasking master. Can he successfully kill two birds with one stone or will he end up getting nothing done?
