Tim thinks he has the most boring family in the world. School is boring too, because they all have to follow a very boring timetable, insisted on by Mr. Dedman, the headmaster. Then the graffiti starts appearing in school: This Building is Full of Chickens, Dedman's Chicken Factory. Who is writing it? Why is Mr. Dedman so apoplectic about chickens? As if the mystery at school isn't enough, Tim discovers his father dressing up as Wonder Woman. Suddenly, boring starts to look very good indeed
