Imagine having your teacher staying at your house for the weekend, while you do the teaching and they do the learning! Kirsten O'Brien and Johny Pitts present the ultimate challenge for Britain's kids and their teachers. The pupils have just two days to teach the teacher all about their hobbies - and the teacher has an exam on Monday in front of the whole class to see if they've been paying attention! This episode's hobbies include skateboarding and dancing like Michael Jackson.
