"The Pope's Limo" joke

One day the Pope is coming to America in his
Limo and he said to the driver, 'Why don't you
let me drive for once.'
The driver thinks to him self, 'Well I can't say
no to this guy, he's the pope.' So the driver
pulls over and they change places. The Pope was
having fun, hauling butt down the freeway, dogging
cars. After a while the driver taps on the window
and tells the Pope, 'slow down a bit, you might
get pulled over.'
The Pope says, 'ahhh, don't worry about it, I'm
the Pope.' So he rolls up the window and
continues to drive very fast. After a few moments
he gets pulled over. The cop walks to the car and
the Pope rolls down the tinted window. The cop
sees the Pope and says, 'oh, I, ehhh, sorry, can
you hold on a minute.'
The Pope says, 'sure'
The cop walks back to his car and radios back to
the station. He says, 'guys I just pulled over
some one really important.'
They ask who, 'The President?.'
'No more important.'
'The president of another country.'
'No more important.'
'An ambassador.'
'No even more important.'
'Well who is it.'
'I don't know, but the Pope is the chauffeur.'
