A soldier ran up to a nun.
Out of breath, he gasped, "Please Sister, may I hide under your robes - I'll explain later!"
The nun granted his request and a few moments later two M.P.s skidded to a halt in front of the nun and asked her if she had seen a soldier running past her.
The nun pointed behind her and told the M.P.s he had gone past her and down the road. The M.P.s thanked her and charged off down the street.
The soldier waited for the sound of running boots to die away and crawled out of his hiding place and thanked the Sister for her help and told her his unit had been posted to Afghanistan and he didn't fancy going.
The Nun said that she completely understood his reluctance.
The soldier said, "Sister, I hope I am not being rude, but you have a really great pair of legs!"
The Nun grinned and told him that, had he looked a little higher he would have seen a great pair of bollocks as she didn't fancy being posted to Afghanistan either!
