Chris Smith is an award-winning author, broadcaster and parent (a mug saying 'World's Greatest Dad' counts as an award, right?). He grew up in leafy Northamptonshire and now lives in not-as-leafy North London with his wife, son and a cat called Mabel, who can talk. If you listen very carefully to the George Michael song 'Outside' you can hear a sample of Chris reading the news. He makes excellent tea. Greg James is also an award-winning author and broadcaster, best known for hosting the Radio 1 Breakfast Show, but he hasn't won any awards for being a parent, because he isn't one. He circumnavigated the M25 during his childhood and is now living with his wife, Bella, and their dogs, Bonnie and Barney, in North London. Greg and Chris's houses are connected by a secret tunnel that they use for exchanging ideas via an elaborate pulley system. He makes terrible tea.
