Steve Douglas gets a parking ticket from Robbie's girlfriend, a pretty meter maid, and another citation for not having his driver's license renewed -- and then flunks his driving test. Soon Robbie realizes that he's given his father last year's manual to study and that some laws have been changed.

Ernie feels left out when the Douglas family orchestra begins to practise. Uncle Charley tries to teach Ernie the violin but runs into a major obstacle -- the boy's lack of obvious talent.
