Back When I Knew Everything

Oh, if I had a big ol' eraser, I’d start from today
And go back through life’s pages and correct a lot of things
Yeah, steppin' on toes with my foot in my mouth
Yeah, thought I was the king but that was back
Back when I knew everything
Yeah, a good hard head and no regrets
Is what I thought made the man
But now life’s hard knocks is about all I’ve got
And sorrys what I am
Yeah, I had my old worn out opinion
Oh, and I sure made it plain but that was back
Back when I knew everything
So what you say forgive and forget one more chance is all I need
Yeah, this ol' loose cannon is a mighty long shot
Bu this time I’m askin' please
Yeah, that’s right I was wrong
Now all that I can say is that was back
Back when I knew everything
A little too big for my britches but life’s a whittled me down to size
I just hope there’s enough of me to left to apologize
So what you say forgive and forget one more chance is all I need
Yeah, this ol' loose cannon is a mighty long shot
But this time I’m askin' please
Yeah, that’s right I was wrong
Now all that I can say is that was back
Back when I knew everything
Oh, that was back
Back when I knew everything
