Gloria went to visit her friend Jenny who had moved to South Africa, some eight years ago.

Jenny took Gloria for a coffee and cake, one afternoon.

It was a beautiful day, so they decided to go for a walk before returning to Jenny's home.

Jenny acting like a tour guide, explained some of the sights as they walked along.

"AND this is the South African Army barracks".

Looking over the low wall, Gloria exclaimed, "That really surprises me. I thought that the South African army were black".

Jenny replied, "Oh no. Only their privates are black".

To which Gloria remarked, "Oh, how exotic".

Funny .

FUNNY
the climax

Let's see if you really understood the joke, why is it funny?
