A priest and a rabbi operated a church and a synagogue across
the street from each other. Since their schedules intertwined,
they decided to go in together to buy a car.
After the purchase, they drove it home and parked it on the
street between them.
A few minutes later, the rabbi looked out and saw the priest
sprinkling water on their new car. It didn’t need a wash,
so he hurried out and asked the priest what he was doing.
“I’m blessing it,” the priest replied.
The rabbi considered this a moment, then went back inside
the synagogue. He reappeared a moment later with a hacksaw,
walked over to the back of the car and cut off two inches of
the tailpipe.
