A failed attempt to comb a hairy 3-ball (2-sphere), leaving a tuft at each pole
Only on a perfect sphere. Imperfections allow for places of overlap
- Damn these perfect balls of mine!
  
  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
Huh?
- You can never have smooth hairy balls, if you have a donut though it can be smooth and hairy.
  
  Yeah you can. Just tuck the last bit into your arse hole.
do chocolate salty balls next
In German, it's called "Satz vom Igel" (verbatim: "Sentence from the hedgehog"). Sounds like some fable. 🙃
