Found this reply on Father Z’s blog:
You better not plan,
You better not frown,
You better not cut some Cardinal down,
Pope Francis is coming to town.
Prometheans and Pelagians too,
all the bad kids are getting their due,
Pope Francis is coming to town.
He hears you spreading gossip,
he knows when you’re on break,
he doesn’t like that cappa,
take it off for goodness sake!
Oh, you better not gripe,
you better not moan,
he’s calling at random – stay by your phone,
Pope Francis is coming to town!
