Penny's Last Name

Think of a random character from any TV show you watch; we bet it will have a full name. Penny doesn't have a full name, though. We all know her as Penny and have no idea what her surname is. It has been nearly a decade since the Season 1 was aired, but Penny's last name continues to remain a mystery! We will be seeing Penny's mother and brother in Season 10 episodes, as the duo will attend Penny's marriage with Leonard. The makers of the show say they will be focusing more on Penny's life in the latest season, so we think they may announce her last name very soon. Penny herself doesn't want you to know her last name, so it's not just the makers of the show who are holding back the announcement.
