Einstein's riddle
Einstein wrote this riddle last century and said that 98% of the world’s population would not be able to solve it.

Are you a part of that 98%?

* There are 5 houses that are each a different colour.

* There is a person of a different nationality in each house.

* The 5 owners drink a certain drink. They each smoke a certain brand of cigarettes and also have a certain pet. No owner has the same pet, smokes the same brand of cigarettes nor drinks the same drink.

The question is. “Who has the fish?”

Einstein did not say that 98% of population can't slove the riddle, he said, that they can't slove it within 30minutes, and he is probably right.
Oh yeah... German has the fish.<--Answer

Solutions in white
Ene Dene,

Normally we put solutions to puzzles and riddles in white (as paultwang has done above) so that they can only be seen when you highlight them with your mouse. I'll edit yours now.
