Walled Nativity
A nativity set with a difference - this year the wise men won't get to the stable.
Well that would just be accurate because the wise men didn't go to the stable in the first place:
7Then Herod called the Magi secretly and found out from them the exact time the star had appeared. 8He sent them to Bethlehem and said, "Go and make a careful search for the child. As soon as you find him, report to me, so that I too may go and worship him."9After they had heard the king, they went on their way, and the star they had seen in the east went ahead of them until it stopped over the place where the child was. 10When they saw the star, they were overjoyed. 11On coming to the house, they saw the child with his mother Mary, and they bowed down and worshiped him.
Matthew 2:7-11
There you go, ruining everyone's hissy fit over this by using biblical facts.
