Penny is an attractive blonde who lives across the hall from Leonard and Sheldon, and she is the force that drives them to experience things outside their protective bubble.

Born and raised in Omaha, Nebraska, she now works as a waitress at The Cheesecake Factory while she waits for her acting career to take off.

She has a close relationship with Leonard, and has often shown a great deal of warmth towards Sheldon, often in the form of mother-son interaction.
