As Kim’s campaign for a car coincides with the need to take Grandaddy Clisby’s keys away, Bill proposes a solution that is only pleasing to him: Kim can drive, so long as she takes her grandfather and Dean around town. Later on at the mall, Dean is worried about seeming uncool when Clisby ends up chaperoning him and his friends, but Clisby has a few crowd-pleasing tricks up his sleeve.

It's the end of the school year, and summer excitement is all around; Bill and Lillian each receive major career opportunities; Dean and Keisa take shelter together as a tornado tears through.

In search of a new hobby, Dean joins the drama club - only to find himself mixed up in drama of his own. Bill and Kim grapple with Bruce's choice to campaign for a local politician.
