Granny goes to the local bowling alley to bowl against the Champ. The Champ doesn't like the fact that he is bowling against a sweet old lady and figures that he will win easily, at least until he sees how well Granny bowls.
Each of the contestant makes one strike after another using various bowling techniques. The Champ likes to use ones that involve Precious getting hit or bowled. Precious then does to the Champ what the Champ does to him.
The game comes down to the last set and all Granny has to do is bowl a strike. She bowls and the Champ throws a switch that puts her ball in the gutter and flings it outside. Precious chases after it and redirects it to the alley where it makes a strike. Granny is crowned the champion.
The Champ grabs the trophy and runs with it. Precious bowls and throws the switch like the Champ did and the ball flies outside and knocks the Champ out cold and Precious returns the trophy.
