Jack'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, Jack would head outside to the porch.

His wife, with hurt feelings, said, "What's the matter, Jack? Don't you like my singing?"

Jack replied, "Honey, I love your singing, but I just want
to make sure the neighbours know I'm not beating you."
