You can guess as many times as you want as long as it hasn't been guessed already.
Well, Pepper Fairbanks?
No, i'm sorry but you're still not right.
You're in the right game, and it's a faceless character.
The Vid-comic narrator?
Nope. It's in ACiT.
Even I don't know this one - but even if I did, I wouldn't be allowed to guess this round anyway!
EDIT: I actually just figured it out, and it is a really obscure one! 
I will try and throw an extended version out with another hint
Captain Qwark's fighting style is a mixture of… crouching kitten and sleeping possum?
It's in ACiT
It's said by a character who is never seen
It's not Ratchet, Kip or Pepper.
This character normally spends most of his time talking about Ratchet…
There is no way anyone can not know it now, surely…

Now I know! Agorian Battleplex announcer!
It's about time…
it's your turn Kubak. I was fearing that I would (yet again) have to come up with a new quote.
I'll do a breathe! Anyone have any gum?
Are you sure that's right Kubak? It sounds a little off. But I wouldn't know because I have no idea where this is from (and of course I can't guess anyway)

I'm sure about the gum part 
Here are two clues:
- Heather might heard it once, twice, or even more times
- You can find this VO clip on YouTube separated, along with other lines by this character from this certain game
I wonder if it is from a canon R&C game?
Screw points It's Gleeber (or whatever the name of the short one was).
EDIT: In PS Move Heroes.

They were Gleeber and Lunk, but it's no one of them. But you and Ratchetruler are going in a right direction…
