Nickelodeon has a hit with the Tween audience with Zoey 101 -- starring Jamie Lynn Spears, l'il sister of "the Brit-ster!" Zoey's first year at a formerly all boys' boarding school continues - or does it? It's Prank Week at Pacific Coast Academy and it's all fun and games until Zoey almost gets expelled for a prank gone wrong. Can the boys and girls stop pranking each other long enough to get Zoey out of hot water with the principal or will Zoey have to say goodbye to PCA?
