There’s a math joke I remember hearing ~10 years ago, I can’t remember the whole thing, but it was something about a mathematician not being able to tell the difference between a coffee mug and a donut, they have the same number of holes so they’re the same shape.
I’d never heard of it either.

Edit:
I also was also told once that since the nostrils and mouth are connected holes which lead to the asshole, humans are homotopic with fidget spinners.
