How does Gordy act like Rowdy?

Gordy comes to Junior's rescue when his teacher chastises Junior for missing school. Junior is too afraid to stand up to Mrs. Jeremy, but Gordy drops his textbook on the floor as a sign of protest. Penelope and the rest of Junior’s classmates follow suit. They all walk out on Mrs. Jeremy, and Junior is happy to have people in his life who want to stand up for him.
