In the mid 80s a cruiser of the U.S. navy put in to port in Catahegna, Spain, for a weeks shore leave. (Well, leave for the crew, not the cruiser.) The first evening, the captain was more than a little surprised to receive the following letter from an upper-class Spanish lady:

Dear Captain,

On Thursday, it will be my daughters coming of age party. I would like you to send four well-mannered, rich, unmarried officers.

They should arrive at 8 p.m. – One last point: no Jews – we dont like Jews.

Sure enough, at 8 on Thursday, the lady heard a rap at the door, which she opened to find, in dress uniform, four exquisitely-mannered, wealthy, single, BLACK officers.
Her lower jaw hit the floor, but pulling herself together she got out There must be some mistake.

Madam, said the first officer, Captain Cohen doesnt make mistakes.
