Lyrics:
There ain't nothin' I can do, or nothin' I can say
That folks don't criticize me,
But I'm going to do just as I want to anyway,
And don't care if you all despise me!

If I should take a notion
To jump into the ocean,
'T'aint nobody's business if I do, do, do!

If I go to church on Sunday,
Then just shimmy down on Monday,
'T'aint nobody's business if I do, if I do!

If my friend ain't got no money,
And I say, "Take all mine, honey",
'T'aint nobody's business if I do, do, do do!

If I give him my last nickel,
And it leaves me in a pickle,
'T'aint nobody's business if I do, if I do!

There, I'd rather my man was hittin' me,
Than to jump right up and quittin' me,
'T'aint nobody's business if I do, do, do do!

I swear I won't call no copper
If I'm beat up by my papa,
'T'aint nobody's business if I do, if I do!
