> What are you doing?
> What does it look like I'm doing?  I'm kicking your ass.

What comes in my mind is not an opening line but a short dialogue between Tony and Ziva in an episode of NCIS:
Ziva is sitting behind her desk with her barefeet on the desk covered by fighting tape (we could still see her toes and heel) and there is some blood on it...
Tony (looking at her feet): Are you hurt?
Ziva: I.am ok. It's not my blood!!!

NCIS, and their writers, definitely "get it". 

In all their (many) fights, they pay attention to all four of:
> The match-up
> The build-up
> Tension
> Release

There was a Catfight Club one from years ago that went:

- Who do you think you are !?

- I'm the bitch that's going to beat you up !

That pretty much covers all the bases.
