Gordo is sure that Mr. Pettus is giving him ""B""s instead of ""A""s because Pettus doesn't like him. His state of mind isn't helped any when the teacher gives the class an aptitude test which shows that Gordo is best suited to be a blackjack dealer. To prove that Mr. Pettus has it in for him, Gordo convinces Lizzie to turn in his science project with her name on it and vice versa, which ends up having disasterous results. Also, Matt adopts a hip-hop attitude and insists that everyone call him ""M-Dogg.""
