Me and my sister both thought for ages that the words to a hymn we used to sing at school "For I am the Lord of the Dance, said he", went "For I am the Lord of the down setee". We were a bit confused about this and worried because we didn't have a setee in our house - did that mean we couldn't have Jesus in our house too?
