Pope Francis in his younger days.
The Holy Father worked in a variety of locations in his native Argentina. For example, as a very junior priest, he would say "Go, the Mass is ended" at the end of a service, and woe betide anyone who refused to leave promptly: they might find themselves leaving on all fours.
