US Navy in Spain joke

In the mid 80's a cruiser of the U.S. navy put in to port in Catahegna, Spain, for a week's 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 daughter's 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 don't 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 doesn't make mistakes."
