Have a look at this riddle. I've never seen anything quite like it, and I am a collector of math puzzles and brain teasers.

 

See if you can solve it without reading the solution (at the bottom of the link). I guess there is a slight hint given in the explanation, and that is that a solution involves the axiom of choice.
