Can anyone solve this?

Einstein supposedly wrote this riddle and said 98% of the world could not solve it...

There are 5 houses painted in different colours in a row on a street. In each house lives a person with a different nationality. The 5 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, nor drink the same beverage.
