Einstein's Riddle

   Albert Einstein is said to have given a riddle. He who solves it, it is said, proves an IQ in the top two percent, and is thus fit to join Mensa. Well, okay, entirely anecdotal Einstein. Let's say we've got five houses, all in a row. I guess there are people living in those houses. This much is known of them.

1. The British person lives in the red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The green house is on the left of the white house.
5. The green homeowner drinks coffee.
6. The man who smokes Pall Mall keeps birds.
7. The owner of the yellow house smokes Dunhill.
8. The man living in the center house drinks milk.
9. The Norwegian lives in the first house.
10. The man who smokes Blend lives next to the one who keeps cats.
11. The man who keeps the horse lives next to the man who smokes Dunhill.
12. The man who smokes Bluemaster drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The man who smokes Blend has a neighbor who drinks water.

Question: Who owns the fish?

   All right. We can immediately rule out the cat owner, since fish in a home with cats in it would not last long. Nor dogs, for that matter. They'd probably just knock that fishbowl over. We know that it's neither of the bird owner nor the horse owner, so the fish owner must be the one remaining. Answer: the fish owner is the one who does not own birds, cats, dogs, or a horse. Elementary.

   Gee, what a stupid question. Mensa can suck it.
