It looks like a duck, it walks like a duck, it talks like a duck, (That is, if ducks could talk. I’m assuming here that ducks cannot talk, but who knows? They could surprise me. This assertion is also conditional on the fact that ducks do not speak any human tongue, and not, in fact, a duck language of its own right, which would still remain unintelligible to me, who, as you know, does not know of any such language and would no doubt put very little effort into learning it.) so it’s a duck. Probably. I could be wrong.
