I have a schnoz just below Cyrano scale. My friend calls it a Roman senator's beak, while my wife claims it's more like a ski slope. I usually interject something like lions have strong noses or that the Romans once controlled most of the known world, which is met with eye rolls or smirks. When people try to guess my ethnicity, they usually say either Jewish or Italian.
