Same sounding word but different meaning! A Daily Mirror story that Kingsmead Technology College in Hednesford, Staffordshire, has introduced pigeon racing into its curriculum because teachers think it can help with maths, physics, geography and biology, had the headline 'A Real Coo'. 'Coo' means the sound made by pigeons and its use here is a play on 'coup' which can be a clever or successful action.
