Someone at work photocopied me this puzzle out of a book she bought, I thought I'd share it with you lot. I haven't managed to work it out yet, by the way, so spoiler everything:
[desc]There are five houses painted five different colours. A person with a different nationality lives in each house. The five house owners each drink a certain type of beverage, smoke a certain brand of cigar and keep a certain pet. No owners have the same pet, smoke the same brand of cigar or drink the same beverage.
Who owns the fish?
1. The Briton lives in a red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The Green house is next to, and on the left of, the White house.
5. The owner of the Green house drinks coffee.
6. The person who smokes Pall Mall rears birds.
7. The owner of the Yellow house smokes Dunhill.
8. The man living in the centre house drinks milk.
9. The Norwegian lives in the first house.
10. The man who smokes Blends lives next to the one who keeps cats.
11. The man who keeps horses lives next to the man who smokes Dunhill.
12. The man who smokes Blue Master drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The man who smokes Blends has a neighbour who drinks water.

Quite cryptic. Apparently there is only one answer, and that it can be reached with the cool application of logic and a lot of patience. It also goes on to mention that it was rumoured to have been conceived by Einstein, and that only two percent of the population are able to work out the correct answer. Good luck!
EDIT: Updated with, you know, information you need to actually solve the riddle.
