Strange Hill High S02 E01 The Curse of the Wereteacher

"It's Weird. It's Cool. It's School!"

Mitchell is bitten by a rabid Deputy Head and, every time the school bell rings, transforms into the disciplinarian were-teacher, Mr. Tanner. If the curse isn't lifted before Mr. Tanner signs a permanent contract, Mitchell could be doomed to spend the rest of his life as a teacher at Strange Hill!
