D.W. and Arthur in “Unfinished Business”

Arthur, I need your help! What can you tell me about kissing?

What? Nothing!

C'mon, you must know something about the birds in the trees. Like, how can I get a boy to kiss me?

I don't know! Ask mom. I'm doing homework.

Oh! You're no help. [finds a book on the ground of two people kissing] Aha! You do too know something about kissing. You have a book all about it.

This is the story of Romeo and Juliet, D. W. It's based on a play by William Shakespeare. We're reading it in school.

And? What's it about?

[sighs] If I tell you, do you promise to leave me alone? [D. W. nods] Okay. [starts talking fast] There's this boy named Romeo and this girl named Juliet and their parents don't like each other, but they fall in love anyway and plan to run away together, but there's a misunderstanding and it all ends badly. The end.

Where's the kissing part?
