World Series of Pawn

Take me out to the Pawn Stars when the guys look at a Los Angeles Dodgers World Series Pennant signed by Frank Sinatra. Will the connection to ol' blue eyes send the price to the moon? Then, a replica of the Delorean from "Back to the Future" flies into the shop. Can they accelerate this deal to 88 miles an hour? And later, when Chumlee keeps losing the shop's keys, Rick has to get creative to break him of the habit.
