Prehistoric Dog

Dogs that howl from outer space [bad word] to Earth to lay to waste
With fang and claw to shred your face
They will erase the human race
Time to kiss your [bad word] goodbye
Prehistoric dogs of war
Pack of wolves is at your door
Their will to kill will fill the pits of [bad word] 
Blood is spilled and none too soon
Looking down from cratered moon
They see us flee we need to break the spell
Dogs that howl from outer space [bad word] to Earth to lay to waste
With fang and claw to shred your face
They will erase the human race
Time to kiss your [bad word] goodbye
Our lives are long
But our flesh is gone
It may be wrong
God bless godlessness
We're walking tall
If we walk at all
We're living like a
