tall girl (Courtney Henggeler) - The Big Bang Theory

Description

Missy is Sheldon's fraternal twin sister who is intellectually much unlike him. Tall and attractive, she immediately catches the attention of Leonard, Wolowitz, and Koothrappali. She refers to Sheldon as 'Shelly', and though she loves her brother and is proud of his accomplishments (though she, much to his chagrin, mistakenly refers to him as a "rocket scientist"), Missy is not above crotch-punching Sheldon to keep him in check.
