you've come to this. bringing den here.
you've come to this. you were a lion.
you've come to this. sigh alone now.
you walked on some tall moon tail.
it's come to this. you walked on a tall.
we all know you've come home to fall.

she's gone, she's gone 'cross the border, man.
and you're never gonna see her again.
i could give a fuck, oh, what you do to me.
but your party's over, it's done. the end.

take a step back
take a step back
take a step back man
take a step back and turn yourself around.
the check has been cashed
there's no stopping it now.
you're safe if i'm safe
and she's safe, we're okay.
the sooner as we pass this
we'll all stop our knocking on wood.
knock on wood.

she's gone, she's gone 'cross the border, man.
and you're never gonna see her again.
i could give a fuck, oh, what you do to me.
but your party's over, it's done. the end.

it's come to this (x8)

and we all know
that you've come home
to fall.

she's gone 'cross the border, man.
and you're never gonna see her again.
i could give a fuck, oh, what you do to me.
just leave her out of this.
