M sends James Bond on a secret mission to heaven. When M doesn't hear from Bond for over a day, he gets worried and calls up heaven.
The Virgin Mary picks up the phone and says "Virgin Mary speaking. "M asks her if Bond has reached there yet. She replies that he hasn't.
M waits another few hours and calls heaven back again. "Virgin Mary speaking," comes the response. "Is James there yet?" asks M. Again the answer is no.
M is really worried by this time but he waits for a few more hours and then calls heaven back again.
"Hello, Mary speaking !"
