If Penny got replaced or left the show. in The Show Posted June 5, 2012 Yes, they could drop the Penny character and have another character perform a very similar function as the Penny character now does. An attractive women who appears to be out of reach for a nerd like Leonard but who eventually sees past his nerdiness to his good qualities or better yet, embraces his being a nerd. As I have mentioned on numerous occasions, there have been episodes where Penny either does not make any appearance at all or appears for only a few minutes in the episode and it did not seem to affect the ratings or the story line. If Penny were to be replaced, I think that they would do well to replace her with someone more emotionally mature and who is more professional in her career. Perhaps a businesswoman or an attorney. I have no idea what Sheldon's twin sister does for a living but if for some reason Penny was replaced, she would be my first choice simply because of the interaction between not only her and Leonard but between her and Sheldon. I don't get it. Leonard has complained about Penny wearing shoes that are too tall and you think Missy, who is about a foot taller than Leonard, would make a good match for him? How is that possible? Also, Sheldon said what Missy does for a living. She works at Fudruckers. Doesn't really fit your business woman/ attorney scheme. We're not talking about a good match for Leonard. We're talking about replacing the Penny character's arch-type. Penny isn't a good match for Leonard either, so yeah, Missy would be a good replacement for Penny. Now, I have no idea what it is about Missy, but she comes off as like way more intelligent and confident and capable than Penny. Like a hundred fold. Maybe it's all just in how she carries herself. Maybe she is, as Sheldon says, dumb as soup.
