You refuse to ship your guy with Celestia, hmm? I must ask, would a one-night-stand after a forgotten day count as this, even when Fluttershy is the intended ship?
 
(Everyone wakes up one day to find that a whole day was skipped. The whole previous day is an absolute blank. To the mutual confusion and embarrassment of Mugen and Celestia, they woke up in bed together, and it was plainly obvious they did SOMETHING scandalous that night.)

Re: Celestia: I see what happened. The tag for that is “s servant interview”, not the tag used on this post.

Okay, next one will be Mayor Mare.
 
About the other suggestions:  
Chrysalis interview: Image 17085  
Zecora: Definitely no, I’m not twisting my brain with rhyming again.  
River serpent (Steven Magnet if I recall that right): Not enough material to work with, so no chance.  
Diamond Dogs: That’s a big maybe, but I might actually do that sometime.  
Any buffalo: Not planned.  
The pets: Nice idea, I’ll keep it in mind.  
Pipsqueak: Again, not enough material.  
TT / Doc Whooves: Interesting Idea, gotta check for material first, though.

How about Time Turner (aka Doctor Hooves)?

Pipsqueek? The pets (with some magical device to allow them to actually answer)?

A second interview of Zecora? Interviewing the river serpent? The Diamond Dogs? One of the buffalo?

@Korra: So many possibilities. Yes, the Mayor is a big one that’s been missed. Or maybe the mule or Hayseed.
 
(I don’t see the Chrysalis interviews on Derpibooru, though.)

@Korora:  
Mayor mare? **facepalm **  
Why haven’t I thought of that before? I’ll give it some thought.

Who’s next? Dinky? The Mayor? Filly ’Shy? Golden Harvest?

@Last BP:  
Thanks ^ _ ^

Having been all over Equestria on her sister’s orders, I think you’d make an excellent escort to Princess Luna. You could quietly explain what’s happening and suggest appropriate responses. (Let’s find a way to have her attend a community veggie barbeque.)

Crap. Missed it. Ah well, nice interview regardless.

Ehmahgerd it feels so fresh to migrate to another account.. shibanana

@CS  
I think I won’t be using this account anymore.  
Check for anyone named OB, by chance

I should make an OC to interact online as well! Ripple Shine, u a genius!

I always love these, CS. Keep’em coming!
 

Stop uploading these when I’m sleeping!
 
j/k, good work as usual.

I like that you avoid (as hard as it is) shipping yourself with the Princess or any other character.That’s professional xD

WHATSOEVER DEVICE  
I’ll have you know that I put a lot of time into the Steam Pressure Engine Manic Pull Master. Or the SPEMPM for short.

But other than that, It’d be a good way to conserve material during the off-season. Like now, for instance.

These reverse interviews aren’t a bad idea, I must say. Only real problem I can see them having, besides format, is that not everyone has an OC/ponysona they use to interact online.

@bomg:  
Actually that’s some weird shaped builing in the background, not a hat. Looks like one though.

Is Celestia wearing a hat in Ripple_Shine’s panel? Looks like it. Besides her crown that is.

Pretty worth it though. Considering how weird the characters can be it’s pretty difficult sometimes to nail it.

That’s what consumes the most time making them. Working out answers in character.
