The Pope was visiting an American. He was trying to get across town without attracting too much attention, so instead of the Popemobile, he was driving in a heavily armored SUV with very tinted windows.
So the chauffeur is driving the Pope around, and the Pope gets to wondering. "Man," he thinks, "I haven't driven in ages, not since I was a bishop." He promptly orders the chauffeur to pull over and get in the back seat. The Pope gets in front, slams his foot down on the gas, and barrels down Main Street.
The Pope is a terrible driver, and extremely out of practice. He crashes into street lights, fire hydrants, small children, everything. Eventually a police car, comes, sirens blaring, and the Pope pulls over.
The cop gets out of his car and taps on the window, and the Pope rolls the window down. The cop and the Pope stare at each other for a while, and then the cop nods and walks back to his squad car. The Pope drives off.
A nearby witness, who has seen the whole thing, runs over to the cop.
"Officer!" he asks, "Why didn't you arrest that man, or at least give him a ticket?"
The cop shakes his head and says: "He's too important to arrest."
The man says: "Who could be so important that they could get away with that?"
The cop replies: "I don't know, but he's got the Pope as his driver."
