Leonard Hofstadter:
[entering Penny's apartment] Hey I was just... what is happening?

Penny:
[Penny dressed in a nightie] Oh, just a little treat. I know you've been feeling really bad about your Mom lately.

Leonard Hofstadter:
Oh, oh, I have. So bad.

Penny:
And I wanted to make you to feel better. So I planned something very special for you.

Leonard Hofstadter:
I can already feel it working. [he starts to drop his pants]

Beverly Hofstadter:
[Penny turns her laptop around and there is Beverly Hofstadter] Hello, Leonard!

Leonard Hofstadter:
[he hurriedly puts his pants back on] Mom?

Beverly Hofstadter:
I understand you have been whining about my parenting in order to emotionally manipulate your girlfriend.

Leonard Hofstadter:
I, uhhh.

Penny:
Bernadette told me everything. Now you don't get the left or the right. [referring to the running joke about his preference for the left in breast-feeding as a child]

Beverly Hofstadter:
[Penny leaves the room] Let's discuss why you continue to involve me in your sex life.

Leonard Hofstadter:
Oh please, mommy. No, mommyyyyy.

Beverly Hofstadter:
When you were six years old you walked in on me and your father naked. I was swatting his bottom with your brand new ping pong paddle.

Leonard Hofstadter:
I didn't dream that?

Beverly Hofstadter:
How did that make you feel?

Leonard Hofstadter:
Penny, come back! I'm sad for real now.
