Thanks to anglicana ecclesia (despite the name, I think it's a Catholic site) for this:
"The Work of the Parish Priest"
During a Eucharistic Congress, a number of priests from different orders are gathered in a church for Vespers. While they are praying, a fuse blows and all the lights go out. The Benedictines continue praying from memory, without missing a beat. The Jesuits begin to discuss whether the blown fuse means they are dispensed from the obligation to pray Vespers. The Franciscans compose a song of praise for God's gift of darkness. The Dominicans revisit their ongoing debate on light as a
signification of the transmission of divine knowledge. The Carmelites fall
into silence and slow, steady breathing.
The parish priest, who is hosting the others, goes to the basement and replaces the fuse.
I have to say it rings bells!
I love this one:
A young man is thinking of becoming a Catholic priest, so he goes to talk to his pastor about the different religious orders. "What can you tell me about the Dominicans?" he asks. "Oh, they were formed in the Thirteenth Century to combat the Albigensian heresy," the priest replies.
"And the Jesuits?"
"They were formed in the Sixteenth Century in response to the Protestant Reformation."
The young man looks puzzled. "So what's the big difference between them?"
"When was the last time you saw an Albigensian?"
