The Big Bang Theory, Season 10

Penny:
So did you wind up sending that machine back?

Sheldon:
I did. You know, I'm not even sure how accurate it was. I took it to the train store, it said everyone was sad.

Bernadette:
[enters the apartment] I finally got Halley to sleep.

Raj:
You know, I just read a study that suggests new mothers are better at sensing emotions for up to two years.

Amy:
It's true. Pregnancy causes physiological changes in the brain that result in increased empathy.

Penny:
Oh, so all we need to do is get Sheldon knocked up.

Leonard:
We can't. He was already fixed when I found him at the shelter.

Sheldon:
Yeah, all right. Bernadette, let's test this theory. What do you think I'm feeling right now?

Bernadette:
Let's see... You're better than us, a little bit sorry for us, but mostly glad you don't have to be us.

Sheldon:
[turns to Howard] Keep filling this one with babies, she's good.
