Sinopsis
Tim Baker's got problems: he's failing maths, banished from Ancient Greece, and confused about what to call Mum's new boyfriend. What makes a good father anyway? Is it strength, courage and - strength! - like Hercules believes? Is it attractiveness? Wisdom? Intelligence? Does it have anything to do with beans? Let the Labours of Larry/Mr Green begin!
