Oh, She's Such a Bad Sister

Sarah came in from shopping for a few family members, Joel included.
He asked, "What did you get me?"
She: Can't tell ya.
He: Tell me!
She: A Barbie in a bikini.
He: (clenching his jaw) I won't appreciate that.
She: A baby doll.
He: Nuh-uh. I won't like that. Now, tell me the truth.
She: Okay......(singing) "My Little Pony, My Little Pony..."
He: Errrgh! Take it back!
She: All right, but you won't have anything from me.
He: Uh-huh! I think you'll get me Lego Star Wars.
She: If I do, do you think I'll tell you?
He: Yes, you will.
