It's April 1st and little Pete has planned the best April Fool's joke ever. With the help of Nona, Monica the KrebScout, Wayne, and surprisingly, Pit Stain and his cronies, he pulls off the mother of all pranks. The butt of his joke? Principal Swinger and a group of eight singers that come to the school annually to promote hygiene.
