Kim A. asks: How did they come up with the standard sizes for shoes? Seemingly arbitrary, there is a crazy logic (and a lot of muddy history giving rise to tradition) behind the numbers assigned to different shoe sizes.

Kevin G. asks: Is it true Houdini died performing a water tank trick? Few people in any field of human endeavor rise to become the unquestioned “top-dog” in their profession in their generation, let alone of all time.

David asks: When did the tradition of rolling out a red carpet for celebrities start? Throughout history, red carpets have led luminaries to momentous events, both good and bad.
