From the blog of Eric Shamblen:
IF YOU HAVE 3 HOUSES AND EACH NEED TO HAVE ELECTRIC, WATER AND GAS CONNECTED, IS IT POSSIBLE TO DO SO WITHOUT CROSSING ANY LINES?
If you are into puzzles and riddles you probably have heard this question by now but if you like to read a full explanation of the answer you might enjoy reading the explanation that he gives and the one that appears on Wikipedia.
Sometimes reading the explanations is almost half as fun as trying to cope with the puzzle.
