I used to believe that in the Christmas song "Winter Wonderland" that the words were "later on, we'll perspire, as we sit by the fire" instead of "later on, we'll conspire, as we dream by the fire." I would get some chuckles by family members when we would sing this song. Even though know the real words now, I still prefer to sing it my way.
