"The Fallen Parishioners" joke

An old priest got sick of everyone in his parish confessing adultery.
During one Sunday's sermon he told them, "If one more person confesses
to adultery, I'll quit!"
Since everyone liked him, they decided to use a code word "fallen"
instead. From then on, anyone who had committed adultery said they had
"fallen." This satisfied the old priest and the parishioners, and
everything was fine for years, until finally the old priest passed
away at the ripe old age of 93.
Shortly after the new young priest settled in, he paid a call on the
mayor. The priest was quite concerned, "You have to do something about
the sidewalks in this town, Mayor. You can't believe how many people
come into the confessional talking about having fallen!"
The mayor started to laugh, realizing that no one had explained their
code word to the new priest.
But before the mayor could explain, the priest shook his finger at the
mayor and said, "I don't know why you're laughing; your wife fell
three times last week!"
