The Pope just resigned? This calls for a limerick!

I imagine he said, “Popin’ ain’t easy. Peace, I’m out,” and then dropped the mic and rolled (Image via Wikimedia Commons).

There once was a pontiff in Rome
Who labored beneath
St. Peter’s dome
But he grew old and gaunt
and said, “Screw it; I do what I want!”
Then 
retired to his sweet summer home.
