The ONLY QUESTION asked is "CAN YOU GUESS THE RIDDLE?" Most people read the lines leading up to the question and think the riddle is "WHAT AM I?" but they're jumping to conclusions about what the question is..Again, the question is "CAN YOU GUESS THE RIDDLE?"

The answer is either: "YES, the riddle is..(ask a question, for example, WHAT AM I?) or "NO, I can't guess the riddle."

Something else: Any question that starts with "CAN YOU.." is answerable with yes or no.

Examples:
Can you count to ten? YES
Can you eat a donut? YES
Can you fly by flapping your arms really fast? NO
Can you kick it? YES, we can.
Can you guess..? YES or NO

No more "answers." Just revel in the wonderment of the truth about this riddle.
