Kindhearted and outgoing, Penny (portrayed by Kaley Cuoco) is Leonard and Sheldon's neighbor across the hallway from the inception of the series, replacing the apartment's former occupant, Louis/Louise, a "transvestite with a skin condition" according to Sheldon. Originally from a small town outside Omaha, Nebraska, she was a waitress and occasional bartender at the local Cheesecake Factory until season seven, and is an aspiring actress. Sheldon describes her as a "good-natured simpleton" and is critical of her dropping out of community college.
