My late brother John once told me of a Nativity play his lad was in. He had the part of the inn keeper but was not happy about it, because he wanted to be Joseph. It transpires that when Mary and Joseph knocked on the inn door, the inn keeper came out and asked what they wanted. Innocently, Mary asked if there was any room at the inn, as they had travelled far. The inn keeper, (my nephew) replied, " Yes course you can, but he's not coming in, 'cos I wanted that part" ! Nuff said!
