Joe's wife likes to sing so she decided to join the church choir. From time to time she would practice while she was in the kitchen preparing dinner. Whenever she would start in on a song, Joe would head outside to the porch.
His wife, with hurt feelings, said, "What's the matter, Joe? Don't you like my singing?"
Joe replied, "Honey, I love your singing, but I just want to make sure the neighbors know I'm not beating you."
