Ruthless lyrics
Who always cooked my steaks and cooked 'em rare, Ruth
When the chips were down who was always there, Ruth
And to whom did I swear up and down I'd always tell the truth
E-del-o-da-la-de who in the world but Ruth

But now I'm as ruthless as can be
Ruthless since Ruth walked out to me
Now I had hopes that someday old Ruth would be my wife
But it looks like I'll be ruthless all my life

Who always made my world so bright and cheery, ol' Ruth
Who always rubbed my back when I was weary, sweet Ruth
Who used to call me every day from a telephone booth
E-del-o-da-la-de who in the world but Ruth

But now I'm as ruthless as can be
Ruthless since Ruth walked out to me
I used to think that me and Ruth would share a happy home
But it looks like I'll be ruthless from now on
