This riddle was said to have been developed by a very young Einstein. It has also been said that Einstein said that 98% of the world would not be able to solve it. I no clear proofs of this, but it is a really good work for the mind. So I present it here. It needs mostly logic, patience and time; but you can solve it quite easily.

Here is the riddle:

In each house lives a person with a different nationality.

These five owners drink a certain type of beverage, smoke a certain brand of cigar and keep a certain pet.
