"Co-Ownership" joke
A rabbi and a priest operated a synagogue and a church across the street from each other. Since their schedules intertwined, they decided to go in together to purchase a car.
They bought the car, drove it home, and parked it on the street between them.
Several minutes later, the rabbi looked out and observed the priest sprinkling water on their new car. It didn't need a wash, so he rushed out and asked the priest what he was doing. "I'm blessing it," the priest explained.
The rabbi considered this a moment, then went back inside the synagogue. Reappearing a few moments later with a hacksaw, he promptly walked over to the back of the car and cut off two inches of the tailpipe.
