• A: What? (thinking "B" said something)
    B: Hm? What did you say? (Didn't hear "A" originally)
    A: What.
    B: Oh, I was asking you what you just said.
    A: I said what.
    B: I know. What did you say before that, I was asking.
    A: Before I asked "what"?
    B: Yes! What you said before that!
    A: I said what.
    B: NO! What you said when I didn't hear you!
    A: What.
    B: Remember? The first thing you said?
    A: Yes! I said what!
    B: What?
    A: Exactly!
    B: No, I don't get it! You said what again?
    A: Yes I did, after the first time.
    B: This is confusing me.
    A: What is?
    B: Yes!
    A: Wait... what?
