Not sure whether this helps the atheist cause, but it might ignite some fun debate. From the BBC:
The atheist posters are the idea of the British Humanist Association (BHA) and have been supported by prominent atheist Professor Richard Dawkins.
The BHA planned only to raise £5,500, which was to be matched by Professor Dawkins, but it has now raised more than £36,000 of its own accord.
It aims to have two sets of 30 buses carrying the signs for four weeks.
The complete slogan reads: "There's probably no God. Now stop worrying and enjoy your life."
