as far as the second riddle in his post, its house numbers, you know the metal numbers you put on your door.
each number is 12 cents
the number 1 (one number) is 12 cents
the number 44 (2 numbers) is 24 cents
the number 144 (3 numbers) is 36 cents
and providing im right, since i still dont have a riddle ill pass it off to warbler who was the one that really got the cow riddle (at least i wouldnt have gotten it if not for his post)
