 For Wilma s birthday, Fred want to give something other than the "usual bouquet of flowers": a baby grand piano. Going to the music shop, he is interested by a genuine "Stoneway" piano. However, as the piano seemed pricey, he seems to give up until a strange character named "88 fingers Louie" offers him the same piano for 50 bucks. Not knowing that this is a "stolen piano", Fred seals the deal and asks Barney to help with the piano. But installing the piano overnight without Wilma knowing it is quite a challenge, especially when a suspicious cop gets in the way...
