Grey's Anatomy, Season 10

[Meredith walks into Derek's office to find him reciting his speech to baby Bailey, who is in his car seat]

Meredith:
I went up to daycare to find my son missing.

Derek:
Yeah, I needed an audience. Look, sit down. Let me go over this again with you, okay?

Meredith:
Oh, no, no, no. I've heard that speech so many times I could do it myself. Stop boring our son.

Derek:
Is it boring? I have 50 scientists from around the world coming here today. It's got to be charming. It's a big deal.

Meredith:
I know it's a big deal, which is why I will get out of your way.

Derek:
Mm-hmm.

Meredith:
Mm-hmm. [takes car seat] And I'm taking my son with me because I don't want his first word to be hypothalamus. [kisses Derek]

Derek:
There are worse first words.
