You're asking the wrong question. The question is why are none of your questions ever relevant?
I was trying to figure out why D seems like a journalist to me. I think many a time his questions end with not one question mark but a hundred question marks. It is as if he is saying, answer me or else.
And what you pointed out is the second thing. He is like a lawyer/journalist thing...
*D in court*D: How are you?
Witness: Good.
D: Are you enjoying your tea?
Witness: Yes, thank you.
D: The china is nice isn't it?
Witness: Yes very lovely.
D: Look at the textures, and the color depth.
Witness: Yes very nice.
D: YOU KILLED YOUR HUSBAND DIDN'T YOU BITCH???
Witness: Oh My Gawd! YES! AAAAAAAAAAH!
D: That is a very nice dress.
How much did it cost you? Is it linear or are there multiple points of entry?
Witness: *head explodes*
*closing arguments*D: Ladies and gentlemen of this supposed jury, I have one final thing I want you to consider. Ladies and gentlemen, this is Chewbacca. Chewbacca is a Wookiee from the planet Kashyyyk. But Chewbacca lives on the planet Endor. Now think about it; that does not make sense!
Why would a Wookiee, an eight-foot tall Wookiee, want to live on Endor, with a bunch of two-foot tall Ewoks? That does not make sense! But more important, you have to ask yourself: What does this have to do with this case? Nothing. Ladies and gentlemen, it has nothing to do with this case! It does not make sense! Look at me. I'm a lawyer defending a major record company, and I'm talkin' about Chewbacca! Does that make sense? Ladies and gentlemen, I am not making any sense! None of this makes sense! And so you have to remember, when you're in that jury room deliberatin' and conjugatin' the Emancipation Proclamation, does it make sense? No! Ladies and gentlemen of this supposed jury, it does not make sense! If Chewbacca lives on Endor, you must acquit! The defense rests.
