Wilma is a celebrity when she gets a shot at the big leagues and becomes a pitcher for the Bedrock Dodgers after nailing a couple of robbers with a melon at the grocery store; however, she and Fred argue over her ambition to pitch for the team because Fred thinks a woman’s place is in the home.

After failing his annual physical, Fred wants to prove to everyone that he is in shape, so he decides to become the first citizen of Bedrock to enter the Rockstone Marathon.
