Nope, you didn't make a fool of yourself! You're right. Congratulations! Did it take you a long time? I never figured it out, but my Nameless One was intelligent enough to solve the riddle for me <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
You should definitely play PS:T. In my humble opinion, it's the best game ever made, FFVII and Fallout 2 following closely behind.
Want another one? This one isn't from PS:T, but from BG2. It's always been one I liked:
The rich need it
The poor have it
But if either of them were to eat it
They would surely die
