A man gets onto a bus and sees a really fit nun. He sits next to her and straight away says "I'd love to shag you up the arse". The Nun looks offended and says "the only man i'd let shag me up the arse is Jesus Christ" and she quickly gets off the bus. As the man gets off the bus the bus driver says "Look mate, everyday at 9 o'clock that nun walks through the park, why don't you dress up as Jesus Christ and then she'll let you shag her". So the next day the man hides in some bushes in the park and at 9 o'clock, sure enough the nun walks past. The man jumps out the bushes and shouts 'I am Jesus Christ, will you let me shag you up the arse". The nun quickly answers yes and they soon start getting it on in the bushes. When they've finished, the man says "I'll tell you the truth, I am just that man you met on the bus yesterday" and the nun says "Thats alright, I'm really the bus driver"
