Franciscans and Dominicans
"Of course, Neighbor", said Brother Tonto, and Brother Diotrophes pushed the mower across the street.
Later, Brother Tonto saw that the Franciscan was yanking and pulling on the engine starter rope. Br. Tonto watched for awhile and went over and asked Br. Diotrophes, "What's wrong?"
Br. Diotrophes cried out, "I can't get this mower started, what's wrong?"
Br. Tonto calmly told the him, "You have to cuss it."
Indignant, the Franciscan friar said, "Now you listen here, I am a Franciscan and if I ever did cuss, and I'm not saying I have, I've put all those words behind me, and I've forgotten what to say."
Brother Tonto smiled as he walked away, saying, "Keep on pulling on that chain and it'll all come back to ya."
