Yeah, I know this wasn't in the original show.
It came from the Season 7 episode Selfless.
But it could have been. And because of the mustard reference at the beginning, I put it between "I've Got A Theory" and "They Got The Mustard Out."
I Will Be His Mrs.
ANYA: Was -- was that weird? That thing earlier with the singing ... and the coconuts.
XANDER (asleep): What? No, it's fine.
Singing can be heard through the balcony window.
COUPLE (O.S.):
Oh no!
MAN (O.S.):
Mustard on my shirt.
WOMAN (O.S.):
Mustard. I'll never get it out.
MAN (O.S.):
My favorite red shirt.
WOMAN (O.S.)
Dry clean it.
MAN (O.S.)
How could you serve --
COUPLE (O.S.)
Mustard.
Anya shuts the balcony door.
She looks fondly at Xander sleeping
ANYA:
Mister Xander Harris, that's what he is to the world outside.
That's the name he carries with pride.
I'm just lately Anya, not very much to the world I know,
all these years with nothing to show.
I've boned a troll, I've wreaked some wrath,
But on the whole I've had no path.
I like to bowl, I'm good with math
but who am I,
now I reply that,
I'm the Mrs., I will be his Mrs.
Mrs. Anya Christina Emanuela Jenkins Harris.
What's the point of loving, I mean except for the sweaty part?
What's the point of losing your heart?
Maybe if your lucky, being a pair makes you twice as tall,
maybe you're not losing at all.
No need to cover up my heart, plus (see above re: sweaty part).
So maybe love is pretty smart, then so am I,
I found my guy
And I'll be Mrs.,
I will be his Mrs.
Mrs. Anya Lame-Ass-Made-Up-Maiden-Name Harris
We'll never part not if we can, and if we start then here's my plan
I'll show him what bliss is, welcome him with kisses
'cause this is a Mrs. who misses her man.
He's my Xander and he's awfully swell, it makes financial sense as well,
although he can be, I'll never tell.
Just stand aside, here comes the bride.
I'll be Mrs., I will be his Mrs.
I will be-e-e-e-e . . . .
