Just found this...
After getting all of Pope Benedict's luggage loaded into the limo, (and he doesn't travel light), the driver notices the Pope is still standing on the curb.
'Excuse me, Your Holiness,' says the driver, 'Would you please take your seat so we can leave?'
'Well, to tell you the truth,' says the Pope, 'they never let me drive at the Vatican when I was a cardinal, and I'd really like to drive today.'
'I'm sorry, Your Holiness, but I cannot let you do that. I'd lose my job! What if something should happen' protests the driver, wishing he'd never gone to work that morning.
'Who's going to tell' says the Pope with a smile.
Reluctantly, the driver gets in the back as the Pope climbs in behind the wheel. The driver quickly regrets his decision when, after exiting the airport, the Pontiff floors it, accelerating the limo to 250 kmph
'Please slow down, Your Holiness' pleads the worried driver, but the Pope keeps the pedal to the metal until they hear sirens.
'Oh, dear God, I'm going to lose my license -- and my job!' moans the driver.
The Pope pulls over and rolls down the window as the cop approaches, but the cop takes one look at him, goes back to his motorcycle, and gets on the radio.
'I need to talk to the Inspector,' he says to the dispatcher.
The Inspector gets on the radio and the cop tells him that he's stopped a limo going 250 kmph
'So bust him,' says the Inspector.
'I don't think we want to do that, he's really important,' said the cop.
The Inspector exclaimed, 'All the more reason!'
'No, I mean really important,' said the cop with a bit of persistence..
The Inspector then asked, 'Who do you have there, the mayor?'
Cop: 'Bigger.'
Inspector: 'An MP?'
Cop: 'Bigger.'
Inspector: 'The Prime Minister?'
Cop: 'Bigger.'
'Well,' said the Inspector, 'who is it?'
Cop: 'I think it's God!'
The Inspector is even more puzzled and curious, 'What makes you think it's God?'
Cop: 'His chauffeur is the Pope!'
