Some children were playing outside near a nunnery.

Flocks of birds would frequently fly over them and shit, at which point the children would yell at the top of their lungs,
"Fuck off! Fuck off!"

The Mother Superior, hearing the foul language, rushed out of the nunnery and confronted them.

"Children," she said, "I'm shocked at your awful language!"

At that very moment, the birds flew over and shit on the Mother Superior who raised both arms and vigorously waved her hands at the birds who immediately flew away.

"See," she said triumphantly to the children, "I didn't use bad language and they still fucked off!"
