Octopuses? Octopi, surely?

  Both are fine. (Octopi is arguably wrong, since octopus comes from Greek, not Latin (where you'd find that style of pluralization), but is used so commonly that it has become part of the language)

    It's interesting, though. When I was a child "octopi" was the classic pluralization exception. There's even the joke, "if the plural of octopus is octopi, what's the plural of whatatwitamus?" I have never seen "octopuses" until today.
