A US Navy cruiser pulled into port in Mississippi for a week's shore leave.

The first evening, the Captain was more than a little surprised to receive the following letter from the wife of a wealthy plantation owner:

"Dear Captain, Thursday will be my daughter Melinda's, coming of age party. I would like you to send four well mannered, handsome, unmarried officers. They should arrive at 8:00 p.m. prepared for an evening of polite southern conversation and dance with lovely young ladies. One last point: No, Mexican's. We don't like Mexican's."

Sure enough, at 8:00 PM on Thursday, the lady heard a rap at the door.

She opened the door to find, in dress uniform, four exquisitely mannered, smiling black officers.

Her jaw hit the floor, but pulling herself together she stammered, "There must be some mistake!"

"On no, madam," said the first officer, "Captain Martinez doesn't make mistakes."
