In February 2009, an atheist group in the UK purchased ad space on the side of 800 buses as well as 1,000 posters on London’s trains that read, “There’s probably no God. Now stop worrying and enjoy your life.” A Christian group, the Trinitarian Bible Society, responded by launching a rival ad campaign splashing a Bible verse, “The fool hath said in his heart, There is no God. Psalm 53:1” (KJV)—along with details on how to obtain a Bible—on 183 buses in London.
