What happens when two sets of parents meet up to deal with the unruly behaviour of their children? A calm and rational debate between grown-ups about the need to teach kids how to behave properly? Or a hysterical night of name-calling, tantrums and tears before bedtime? Boys will be boys, but the adults are usually worse – much worse. Winner of the 2009 Tony Award for Best Play, God of Carnage is a comedy of manners without the manners.
