Rick and the Heartbreakers - S17.E4

Rick and Chum try to work out a deal on an old weight loss device. Will they set a personal best, or feel the burn? Then, a seller comes in with a sketch signed by Tom Petty. Is the signature at the top of the charts, or will it be a heartbreaker? And later, Chum connects to the other side when a Ouija board lands in the shop. Will the spirits align for a deal, or end up haunting the shop?
