Kaley Cuoco is an American film and television actress and singer. She is best known for her roles as Bridget Hennessy on the sitcom 8 Simple Rules, Billie Jenkins on the supernatural drama Charmed, and Penny on the sitcom The Big Bang Theory.
Rules are important: just add an all-male group of people and characters and only ONE female! Not 2, not 3, only one girl or woman! Reverse Smurfette Principle groups (where a group of girls had one boy) and double Smurfette Principle groups (where there are two girls in a group of boys) are fine!
