VATICAN CITY, VATICAN - MARCH 12:  Black smoke billows out from a chimney on the roof of the Sistine Chapel indicating that the College of Cardinals have failed to elect a new Pope on March 12, 2013 in Vatican City, Vatican. Pope Benedict XVI's successor is being chosen by the College of Cardinals in Conclave in the Sistine Chapel. The 115 cardinal-electors, meeting in strict secrecy, will need to reach a two-thirds-plus-one vote majority to elect the 266th Pontiff.  (Photo by Peter Macdiarmid/Getty Images)
