Oooh! This is going to be fun!

From the BBC:

The Pope is to resign at the end of this month in an entirely unexpected development, the Vatican has confirmed.

The 85-year-old became Pope Benedict XVI in April 2005 following the death of John Paul II. The reasons behind the pontiff's surprise resignation have yet to emerge.

At 78, the former Cardinal Joseph Ratzinger was one of the oldest new popes in history when elected.

I wonder which particular embarrassing scandal it might have been? The mind boggles.
