Disclaimer: no offence intended to Americans, Australians, or any other group! It's all part of the puzzle.
What am I talking about in the following riddle?
There are many different types of men;
They often come in groups of two or three.
Each group has a matching group of women,
But they should stay with their compatriots.
In Europe we have several different kinds;
The Americans are only half as good as us.
Those from Down Under are all thin and weedy,
Not as tough as the solid British men.
The French can have a woman in their group;
The Israelis won't fit into any other land;
But if you need translation services,
I can provide you with a magic cube.
