Online betting outfit Paddy Power is offering 4-1 odds that God exists. So far, folks have wagered $5000 on the question. Interest has increased resulting from an atheist ad campaign on London buses with the slogan: "There's probably no God." From The Telegraph:
A spokesman for Paddy Power said that confirmation of God's existence would have to be verified by scientists and given by an independent authority before any payouts were made, however.
He added: "The atheists' planned advertising campaign seems to have renewed the debate in pubs and around office water-coolers as to whether there is a God and we've seen some of that being transferred into bets.
"However we advise anyone still not sure of God's existence to maybe hedge their bets for now, just in case."
