why is a raven like a writing desk?
A riddle. From the Lewis Carroll classic, Alice In Wonderland. Carroll himself said "the riddle has no answer, unless it does. But it doesn't, however it might." the riddle is unsolved, except in China. They know everthing. It is often used to confuse or befuddle a friend.
