The hairy ball theorem
Honestly, it's a thing.
The hairy ball theorem of algebraic topology states that there is no nonvanishing continuous tangent vector field on even-dimensional n-spheres.
Huh?
This is famously stated as "you can't comb a hairy ball flat without creating a cowlick", "you can't comb the hair on a coconut", or sometimes "every cow must have at least one cowlick."
Oh, I get it. Right. Hairy ball theorem
