There are 5 houses each with a different color. Their owners, each with a unique heritage, drinks a certain type of beverage, smokes a certain brand of cigarette, and keeps a certain variety of pet. None of the owners have the same variety of pet, smoke the same brand of cigarette or drink the same beverage. Was this the Einstein Puzzle you were talking about?
BTW, I also solved Einstein's Problem that supposedly only 2% of the population could solve. I can post it up if you havent heard of it. That one took me like 4 hours to solve.
