One of my favorite Christmas memories is a Sunday School party we had at our house back in 1980.  Our pastor and friends from that little church in Lexington gathered at our home for a time of food and fellowship.  We topped it off by doing some Christmas caroling in the neighborhood.  But, as we opened our mouths to sing, we somehow got the words of the song we were singing with the melody of another one.  It caused us all to laugh, but the words we were singing were still meaningful, and the neighbors applauded.
