“Why is a raven like a writing desk?”
...asks the Mad Hatter of Alice.
So powerful is humanity's need to solve a mystery that Lewis Carroll, author of Alice and Wonderland, felt it necessary to create an answer to his made up riddle to satisfy his reader’s curiosity:
“Enquiries have been so often addressed to me, as to whether any answer to the Hatter's Riddle can be imagined, that I may as well put on record here what seems to me to be a fairly appropriate answer, viz: 'Because it can produce a few notes, tho they are very flat; and it is never put with the wrong end in front!' This, however, is merely an afterthought; the Riddle, as originally invented, had no answer at all.” — Lewis Carroll
