Alice in Wonderland (Tim Burton's)

Because they're using an english with a solid Bri'ish's accent... I didn't get the answer of this question:

"Why is a raven like a writing desk?"

And below is the conclusion I've got from googling for about an hour.

"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."
