Actually, the answer is yes. You CAN guess the riddle, but your guess isn't really the correct answer. As long as you take a guess, you CAN guess it. I know it's not supposed to be the answer, but it SHOULD be the answer. You see, guesses aren't always correct. I can guess that the square root of pi is 1.47983 and still get it wrong. Do you see what I mean? It's a guess, but it's not the correct guess, which is why the answer to this riddle should be "yes".
