After Mrs. Drysdale complains to Granny they have a physical brawl. It leads to Jethro explaining to Jed and Granny about TV wrestling. While watching Granny thinks its real so she decides to rescue Rebecca, one of the performers.
It's bad enough that Granny gets into a fight with Mrs. Drysdale, but when she watches a wrestling match on TV, that really gets Granny riled up. She gets so upset seeing the "Beast of Boston" beat up Rebecca of Donnybrook Farm that The Beast won't know what's she's in for when Granny decides to help her.—Dionysius Exiguus
