Legend has it that Albert Einstein made up this riddle when he was a kid.

Five houses painted five different colors stand in a row. One person of a different nationality lives in each house.

But none of the owners drink the same beverage, smoke the same type of cigar, or have the same pet.

Watch out though — not all of the cats are the same.
