Is why is a raven like a writing desk rhetorical?

It has been suggested that a raven is like a writing test because both are very annoying. But perhaps it is because both are characterised by the mindless parroting of the utterances of others.

When Lewis Carroll originally posed the question it asked why a raven is like a writing desk, not test. It didn't have an answer and Carroll didn't intend it to, but so many people asked him what the solution was that, two decades later, he offered the following, "'Because it can produce a few notes, though they are very flat; and it is nevar put with the wrong end in front!"

Some years after that Sam Loyd proposed the solution which is the most popular today, "Because Poe wrote on both."
