Reply to me on Messenger with the name of the fourth son.

If you guess and make the mistake, the penalty is simply to post the puzzle yourself.

Can YOU answer this question? (No need to send it on messenger! 😂)

The name of the fourth son and the answer to the riddle is “What”.
Many people think the answer is “Someone”, but if you look more closely at the riddle you will see that there are no question marks afterwards, which makes “What” his name and not a question.

This riddle is, most likely, developed from the “Abbott and Costello” sketch «Who’s on First?»
