My son was in a Christian school Christmas program when he was in kindergarten or 1st grade. There was a set of twins named Timora and Johna also in the program. They had new skirts for the program (when I was little, my mother wouldn't let me wear skirts because I had no hips to hold them up). The girls had a lot of fun with those skirts. During the program they slipped their arms inside the skirts at the waistband and then proceeded to raise their arms and lift the entire fronts of the skits in the air. They were waving with their skirts.
Here all the kids were singing songs about Jesus and His birth. The teachers were sitting on the front pew going crazy about the waving skirts. One of the teachers finally got up on stage and told the girls to stop. They had been oblivious about causing any problem. They were just having a good time with new skirts.
Now here I am 26 or so years later, and I still have that memory. Those girls made quite an impression.
