Chouji was fat.
But to him, it was only puppy fat or he was big boned. What was so great about being skinny anyways? So what if they got all the girls? So what if they were in better shape? So what if they didn't trigger traps because they were klutzy?
Chouji thought maybe he should go on a diet. He could try Atkins or the subway diet. He liked subway. He decided he needed the gear and went up to his room to find workout clothes. He found a bag of BBQ chips. Chouji decided he would start tomorrow.
