There are some as are what they are. And there are some as aren't what they seem to be. And there are some as only seem to be what they seem to be.
Neil GaimanThere are four simple ways for the observant to tell Mr. Croup and Mr. Vandemar apart: first, Mr. Vandemar is two and a half heads taller than Mr. Croup; second, Mr. Croup has eyes of a faded china blue, while Mr. Vandemar's eyes are brown; third, while Mr. Vandemar fashioned the rings he wears on his right hand out of the skulls of four ravens, Mr. Croup has no obvious jewelery; fourth, Mr. Croup likes words, while Mr. Vandemar is always hungry. Also, they look nothing at all alike.
