Moze's math class gets a very nervous student teacher, Mr. Dren, for a few weeks, and he gets pelted with random objects by the class. In Moze's math class, Loomer shines sunlight off his watch into Mr. Dren's face. Moze uses another student's sunglasses to reflect the light back into Loomer's face. Moze asks Mr. Dren if they could go over the last lesson, but backs down when the other students get mad. Mr. Dren asks Albert a question he doesn't know, and he asks Ned for help. Ned gives him the wrong answer, and upon realization, he and the Oboe twins quit the math group.
