Note: I got this story from an email from a former work colleague back in the Philippines.
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.'
