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.
