The pope flies in for an emergency visit.   His plane is late, very late.   Pope sprints out of the terminal at Kennedy, jumps in his limo.

"Can't you go any faster?" he says.
Driver shakes his head.   "Sorry, Your Holiness, but one more ticket and I lose my license."

They go along, doing the speed limit.
"I've got a speech to give, " the pope says, "World peace depends on my being there on time."

"Please, Your Holiness, I lose my license, I lose my job, I got a family to feed."
"Stop the limousine," the pope says.   "Get out and trade places with me."

Pope gets behind the wheel, the driver gets in back.   Off they go, 90, 100 miles an hour till the pope hears the siren.   Pulls over.   Cop walks up to the limo.   Sees the pope, almost faints.   "Forgive me, Holy Father, I had no idea who was in this limousine, please feel free to go."

Pope takes off, tires squealing.   Cop gets on his radio.
Says, "You can't believe who I just pulled over."

"The governor?"
"Much bigger."

"The president?"
"Bigger.   Way, way bigger.   The most important man in the world."

"The most important man in the world?   What's his name?"
"I don't know, but I'll put it this way: He had the pope driving his limousine."
