Bart does not have a twin brother, just two sisters, Lisa  & Maggie.   There was a Treehouse of Horror segment where he had a  conjoined twin named Hugo, but the ToH epiâ¦sodes have no  bearing on the series as a whole.
Despite Missy and Sheldon being twins they are very different both intellectually and socially. Courtney has only appeared in one episode of The Big Bang Theory - The Porkchop Indeterminacy. Missy Cooper (Courtney Henggeler): Missy is Sheldon's twin sister who is intellectually and socially very much unlike him. Confident, tall and attractive, she immediately catches the attention of Leonard, Howard, and Raj. Sheldon realizes that within Missy's eggs lies the potential for another superior mutation like him.
