Lossie, late 70's. Formal dinner in the Sgt's mess. Harry who was black as the ace of spades was there and well known for his whit, he confirmed the following exchange.
Loudmouth - "So Harry, imagine this scene 100 years ago, you could well have been my slave"
Harry's retort "Agreed, and you may well have been my dinner"
Loudmouth left, Harry got lot's of beer!!
