Keith is held in a mental asylum. He's obsessed with box fresh trainers and used to have over a thousand pairs. Every night, once asleep, the asylum porters have to take his trainers and clean them up so they look brand new, then in the morning he is presented with the trainers as though they are brand new and that keeps him happy for the rest of the day. He goes around showing everyone his crisp new trainers and talks about his collection all day long. We don't know how it got to this or what happened to his collection.
