It’s time for the yearly bag-off competition between Rigby’s grocery store and the store owned by Chris’s nemesis–Angus’s Food Barn. It looks like Rigby’s will lose for the 18th year in a row until Kel unknowingly reveals his bagging skills and becomes a Rigby’s employee. Nervous about the competition, Kel and Kenan come up with a sure-fire way to win. A day before the competition, Kel is bribed by Angus to come work for him. Distraught, Chris prepares to lose again–until Kel reveals the boys’ master plan.
