Codename: Kids Next Door, Season 6

Numbuh 3:
[Cheerfully] So, what are we gonna do tomorrow, Numbuh 1?

Numbuh 1:
Uh, I'm not going to be here, Numbuh 3.

Numbuh 3:
Oh. Then what about the day after that?

Numbuh 1:
Uh, let me explain, Kuki-

Numbuh 3:
[Still cheerfully] Oh, I know you're leaving, silly! What do you think I am? An airhead or something?

Numbuh 1:
[Smiles, then says gently] Never for a second.

Numbuh 3:
[Tears in her eyes] We're gonna miss you a lot, Numbuh 1.

Numbuh 1:
[Tears in his eyes] I'm going to miss you too, Kuki.

[Numbuh 3 kisses Numbuh 1 on the head and walks away.]
