A small, uncertain, and nervous witness was being cross-examined.
The lawyer thundered, "Have you ever been married?"
"Yes, sir," said the witness in a low voice. "Once."
"Whom did you marry?" the lawyer demanded.
"Well, a woman," the witness answered timidly.
The lawyer said angrily, "Of course you married a woman. Did you ever hear of anyone marrying a man?"
And the witness said meekly, "My sister did."
