The Doctor and Amy Pond in “A Good Man Goes to War”

[to Melody Pond] It's okay, she's still all yours. And really you should call her "Mummy", not "Big Milk Thing".

Okay, what are you doing?

I speak Baby.

No, you don't.

I speak everything. Don't I, Melody Pond? [Melody gurgles, the Doctor straightens his bow tie] No, it's not. It's cool.
