Rats

I'm starting to notice all of these tails on people I know 
And they weren't there over an hour ago 
My ears are ringing with the sound of squeaking 
And I swear I may be the very last man on earth 
I smell a rat 
I smell a slew of them 
Skittering around the ceiling and the ground 
And its not myself 
So it must be everybody else 
I smell a rat 
Board the doors, I'm staying in tonight 
Won't give in, give up, without a fight 
Pick up an axe 
Its time to fight for my life 
I've got no one to come home to
