When Fred and Barney accidentally come into possession of $86,000 from a bank robbery, they are pursued by both the crooks who stole the money and the Bedrock police.

To commemorate his 10th wedding anniversary (which he only remembers because it falls on "Trash Day"), Fred wants to buy Wilma a Stoneway piano, but after unsuccessfully dealing with snooty clerk Frank Nelson in a high-end music store, he finds a great deal from a shady, cash-only businessman named "88 Fingers Louie." Fred later realizes that it's more than he bargained for. This episode includes the catchy "Happy Anniversary" tune, sung by a quintet of four police officers and Barney, who is also playing the piano.
