          I've thought about this a few times, but tbh I don't know enough about human anatomy to know! My main thing is, what about nostrils? Do nostrils increase the number of (topologically nontrivial) holes in a human? I think we can ignore the windpipe and lungs, there should be a homotopy removing them (I think). Same with eyeballs, vaginas, and whatnot. But nostrils? I think those might be topologically nontrivial.

            Oh! I forgot about ears! Really, the whole sinus situation is complicated and I have no idea what's happening in our weird-ass skulls

              The outer ear ends at the eardrum, so I don't think it's topologically significant either. That said, the nostrils and mouth absolutely connect, so you have at least three holes up there.

              I think we have five topologically significant holes? Nostrils, mouth, anus, urethra. Nothing else is actually a hole.

                  Sorry, I should've said we have five significant orifices. You're right that mouth-anus is one hole.

                How do eye sockets fit into this? Aren't there openings between the skull and outside, technically, even though intraocular muscles or whatever usually keep the eye in an airtight position in the socket?

                  Well, if we're saying that tissue blocking the way doesn't count, then we have a whooole lot of holes.

            Fun fact humans humans topologically look something like a menorah.

      Step one: assume the centrist is a perfect sphere in a perfect vacuum

      How else are they going to stick their head so far up their ass?

      I all but guarantee that if that poster is old enough, they have a mostly-unread copy of Infinite Jest and a "Church of the Subgenius" sticker on an old laptop somewhere and think it's super cool to be vague and pretentious while not actually standing for anything but their own sense of superiority.
