A priest and a rabbi are old friends who enjoy ribbing each other.
The priest says to the rabbi, “Too bad in your business, there’s no room for moving up. Once a rabbi, always a rabbi.”
The rabbi asks, “And in your line of work, you can move up?”
“Well, if I work really hard, I can become a bishop.”
“Huh. And then what?”
“If I play my cards just right, I just might become a cardinal.”
“Huh. And then what?”
“Well, after that, it’s possible that I can actually become pope!”
“Huh, and then what?”
“What do you mean, and then what? I can’t become God Himself!”
“One of our boys made it!”
