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.
“And what on Earth do you intend to do with that?” the priest asked.
“I’ve decided that I want to bless the car too,” the rabbi replied.
He promptly walked over to the back of the car and sawed two inches off the tailpipe.
