Why is a raven like a writing desk?

It isn’t. A writing desk has different coloured feathers.

(There is a clue there.)

the can both be ink black (if you spill ink on a desk obviously). That’s probably not it but it’s a thought

In Carrol’s day they still used quills to write.

(Another clue.)

Homework is best left for www.milkandcookies.com

Function requires feathers? See ya….Gary/wtf

I don’t generally have much confidence in what I find at WikiAnswers, but this seems pretty definitive. I note that this answer is closed to changes.

The notes they produce are both exceedingly flat.

Because Poe wrote on both?
