one time my religion teacher who has a monobrow asked me “what the hell did you do to your hair?” because i had a blonde streak through it and i said “what the hell did you do to your eyebrow” and he sent me outside
when i came back in he asked everyone what monotheism was and i said it meant a religion that worshiped one god because mono means one as in monobrow and he sent me out again
