Monobrow.com is a website that celebrates "the unity of eyebrows." It thinks that people with one eyebrow (isn't that used to be called unibrow?) are cool ;)
My favorite is their Mono Bro of the Week: This one is New York cabbie Azize Hasad whose symmetry of eyebrow and moustache is downright genius.

UNI comes from "unus" (Latin for "one")
MONO comes from "monos" (Greek for "one")
They used to teach things like this in school.
