On a city street, stranger accosts stranger with a mimeographed sheet of paper and the question "Have you seen this?" In university dormitories, the problem is tacked to doors. In suburban households the ring of the telephone is likely to herald a voice that asks, "Is it the Norwegian?" The cause of the excitement is the brain-teaser below. The facts essential to solving the problem--which can indeed be solved by combining deduction, analysis and sheer persistence -- are as follows:

1. There are five houses, each of a different color and inhabited by men of different nationalities, with different pets, drinks, and cigarettes.
2. The Englishman lives in the red house.
3. The Spaniard owns the dog.
4. Coffee is drunk in the green house.
5. The Ukrainian drinks tea.
6. The green house is immediately to the right of the ivory house.
7. The Old Gold smoker owns snails.
8. Kools are smoked in the yellow house.
9. Milk is drunk in the middle house.
10. The Norwegian lives in the first house on the left.
11. The man who smokes Chesterfields lives in the house next to the man with the fox.
12. Kools are smoked in the house next to the house where the horse is kept.
13. The Lucky Strike smoker drinks orange juice.
14. The Japanese smoke Parliaments.
15. The Norwegian lives next to the blue house.

NOW, who drinks water? And who owns the zebra?

Btw, I figured it out in about 1/2 hour.
