Opporknockity A family in the suburbs of Connecticut had a young daughter who loved to play the piano. One day, her parents listened and thought, ""We'd better get that piano tuned."" So they called up a famous piano tuner named Opporknockity, who came over right away and their piano was good as new. The very next day, the girl's little brother sat on the bench and banged on the keys and the strings so hard that the piano went right out of tune again. So their dad got on the phone and asked the piano tuner to please come back over. He sighed and said, ""Opporknockity tunes but once.""
