    Only on a perfect sphere. Imperfections allow for places of overlap

        Where do you keep them? Because if they’re supported by, or attached to anything, or affected by gravity or pressure, I’m sorry to burst your bubble, they aren’t perfect

      You can never have smooth hairy balls, if you have a donut though it can be smooth and hairy.

    In German, it’s called “Satz vom Igel” (verbatim: “Sentence from the hedgehog”). Sounds like some fable. 🙃
