(dwight yoakam)

Chorus:
What I don't know might not hurt me
If I stay dumb and no one tells
But if I find out that you've been cheatin'
What I don't know might get you killed

Death row in prison don't look half as bad
As a life filled with heartache over you
So if you're a playin' those dirty little games
You better pray that I don't find out the truth

Chorus:
'cause what I don't know might not hurt me
If I stay dumb and no one tells
But if I find out that you've been cheatin'
What I don't know might get you killed

Smith and wesson juries hold a real mean, nasty court
And the verdict that they pass is never slow
So keep on a wearin' that little poker face
'cause soon enough your cards will have to show

Chorus:
And I don't know might not hurt me
If I stay dumb and no one tells
But if I find out that you've been cheatin'
What I don't know might get you killed
