Logic Puzzle, Supposedly from Einstein...

 ... but there's no evidence for that. The puzzle originally had folks smoking cigarettes. Yuck. I've changed that to eating candy.

The situation:

• There are 5 houses in five different colors.
• In each house lives a person with a different nationality.
• These five people drink a certain beverage, eat a certain candy, and keep a certain pet.
• No one has the same pet, eats the same kind of candy, or drinks the same beverage.  

 

The question is: Who owns the fish?

 

 

Hints:

• the Brit lives in the red house
• the Swede has a dog
• the Dane drinks tea
• the green house is on the left of the white house
• the green house's owner drinks coffee
• the person who snarfs M&Ms has birds
• the owner of the yellow house loves peanut butter cups
• the person living in the center house drinks milk
• the Norwegian lives in the first house
• the person who adores Heath bars lives next to the one who keeps cats
• the person who has a horse lives next to the peanut butter cup lover
• the person who eats Snickers bars drinks beer
• the German eats Almond Joys
• the Norwegian lives next to the blue house
• the person who eats Heath bars has a neighbor who drinks water

 

[There is one thing that's unclear: Is "the first house" the one on the left of the bunch? I assumed that. Apparently, you can assume that it's on the right end, and according to Wikipedia, you'll get the same answer. I haven't explored that.]
