Give fun a chance! Surprise your mum with a chainsaw, be a bigger star than Tom Cruise, save the world with a plate of vegetables, start your new life in a taxi, rescue your family with a tomato, send your dad into a panic with a tractor, do a good deed with a paper bag on your head, pack your suitcase for a trip to the spleen, upset your auntie with ten kilos of chocolate, swap a bomb for three ice creams on a steam train . . . and lots more.
