I loved sorting through the solutions (and reading the related explanations) for Friday's riddle, so here'sÂ a new one forÂ this weekend'sÂ Weekend Genius Challenge:
Be it days or nights ItÂ measures our slumber But with letters inÂ order It is THE only number WHAT is it? And WHY?
As with many riddles, they may be multiple near-correct answers, but of course, we're only looking for one. Send us your guess by commenting to this post, and please remember that submissions are moderated, so your post will NOT show up right away. If you're the first to correctly match our answer, you'll win a T-shirt of your choice from the mental_floss store. And my undying admiration.
