A woman was singing. One of the guest criticized the singer to the man beside him.

　　"What a terrible voice." He said. "Do you know who she is?"

　　"Yes." the man beside him answered. "She is my wife."

　　"Oh, I'm sorry." he said. "Of course her voice is not bad, but the song is too bad. I wonder who wrote that awful song."

　　"I did." said the man.
