: Sheldon’s attempt to "upgrade" his sister reflects his lifelong struggle with social boundaries and his view of intelligence as the ultimate metric of human worth.

He uses his twin sister, Missy, as his first test subject, attempting to teach her advanced calculus through "operant conditioning". His methods—which include threatening to damage her Cabbage Patch doll—eventually lead to Missy punching him in the face.
