Who's Who

Okay kiddo, "who's who" is like a list of names of important people. You know how in school you have a class list with all your friend's names on it? "Who's who" is like a class list for really famous and important people, like movie stars, politicians, and scientists. It helps us keep track of who's important and what they've done in their lives. It's kind of like a really fancy phone book, but instead of phone numbers, it tells us about people's lives and accomplishments.
