I Cain't Say No -Oklahoma!

Ado Annie is a such a great character! She doesn't abide by what is considered prim and proper. She's unabashedly true to herself, considerate of her gentlemen callers and a bona-fide romantic. 
In the 1955 movie she is portrayed by Gloria Grahame who plays her brilliantly, balancing both an air of disinterest and charm. See the movie clip below! I particularly love how she hardly ever opens her mouth throughout the whole song.
You can sing in your best Southern-style Oklahoma-y accent and there's a fun bit of character acting in it too. Have fun with it!
Here are the lyrics:

It ain't so much a question of knowin' what to do
I knowed what's right an' wrong since I been ten.
I heared a lot of stories an' I reckon they are true
About how girls are put upon by men.
I know I mustn't fall into the pit
But when I'm with a feller, I fergit!

I'm just a girl who cain't say 'No'
I'm in a turrible fix!
I always say 'Come on, let's go!"
Just when I oughta say 'Nix.'

When a person tries to kiss a girl
I know she oughta give his face a smack!
But as soon as someone kisses me
I somehow sorta wanna kiss him back!

I'm just a fool when lights are low
I cain't be prissy an' quaint
I ain't  the type that can faint
How can I be what I ain't?
I cain't say 'No!"

Whatcha gonna do when a feller gets flirty
An' starts to talk purty
Whatcha gonna do?
Sposin' that he says 
that your lips are like cherries, 
Or roses, or berries?
Whatcha gonna do?
Sposin' that he says
That yer sweeter 'n cream
and he's gotta have cream or die? 
Whatcha gonna do when he talks that way?
Spit in his eye?

I'm jist a girl who cain't say 'No'
Cain't seem to say it at all
I hate to disserpoint a beau
When he is payin' a call!

Fer I while I ack refines and cool, 
A settin' on the velveteen setee
Nen I think of thet ol' Golden Rule, 
And do fer him what he would do fer me!
I cain't resist a Romeo
In a sombrero and chaps
Soon as I sit on their laps
Somethin' inside of me snaps
I cain't say 'No'!
