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 as well.” the rabbi replied. He promptly walked over to the back of the car and sawed two inches off the tailpipe.

A rabbi and a priest meet up after a year not seeing each other. The rabbi goes: "Man, you've put on some weight since last time!" Priest: "Yeah I know, it is a new technique I came up with. You go to a restaurant, eat as much as you can. When the bill comes, you tell them you already paid for it." Rabbi: "Sure, but the waiter won't believe you, right?" Priest: "Of course he won't. That's when you tell him how dare he doubt a man of faith? It usually works and you can leave without paying." Rabbi: "Very nice, I'll be trying this." Later that day, the rabbi goes to his favorite kosher restaurant. After eating 5 plates, the waiter comes up to him with the bill. Rabbi: "Oh, I already paid." Waiter: "Mmm, I'm pretty sure you did not sir." Rabbi: "You know I'm a rabbi, how dare you doubt a man of faith? I told you, I already paid." Waiter: "So sorry sir, you are right, it must be some misunderstanding, you're good to go." 15 minutes goes by and the rabbi is still at the table. 30 minutes... 45 minutes... 1 hour and he is still there! The waiter walks up to him: "Sir, why are you still here?" Rabbi: "Well, I'm waiting for the change!"
