Given that we're being inclusive of all Mollusks, octopuses (not "octopi" though "octopodes" is technically acceptable even if it makes you sound like a pedant) are fair game and so this one was unavoidable. And while this version doesn't quite have the orchestration that the original does, the video is much more fun. They must have had a great time making the muppets for this one.
There is a number, somewhere between 10 and 30, that I can no longer remember. It's how many They Might Be Giants concerts I've been to. Yup. Every single one was worth it and a blast.
