One hundred percent pure fool

Well I'm one hundred percent not ninety-nine and nine tenths
Hundred percent pure fool
I wasn't very good at fractions back in school
But I know what I am I'm one hundred percent pure fool

I guess I wasn't thinking guess I lost my head
I stayed out a drinking while you were home in bed
You were making coffee when I came stumbling in
And it's painfully clear I've been a perfect fool again
Yes I'm one hundred percent...
Strung out honky tonkin' a foolish man it seems
Leaving you at home dear alone with just your dreams
Now you could take me back and forgive me if you can
But I won't blame you for leaving cause you know just what I am
Yes I'm one hundred percent...
Well I know what I am I'm one hundred percent pure fool
