Sampo, nicknamed 'Shampoo' by his classmates, is the unspoken school delinquent. He isn't the type to get into trouble but when he does, all he can do to fight back is talk himself out of them. Somehow, even with his barely passing grades and constant skipping class, he still evades punishment from both his teachers and his parents. He's seen as a bit of a lost cause; no one really bothers with trying to 'fix him' from his misbehaviour.
