I try to live my life, live my life everyday
Keep out of strife, come what may
I try to do unto others as I'd have them do to me
But it can't be done for everyone
And now it's plain to see

You are a rat, rat, rat, rat
A big fat hairy rat
Say it ain't true but I'm here to tell you
You're a motherfucking rat
You are a rat, rat, rat, rat
A motherfucking rat (Fuck you!)
Everybody knows from your head to your toes
You're a big fat dirty rat

I try to be real nice, say it twice
Be real nice
Even though it is hard to keep up this facade
And now I see, deary me
What a hassle this could be
I'm out of luck, don't give a fuck
'Cause you're the rat, not me
(Why don't you go fuck yourself, dickhead?)

You are a rat, rat, rat, rat
A big fat dirty rat
Say it ain't true but I'm here to tell you
You're a motherfucking rat
You are a rat, rat, rat, rat
A motherfucking rat
Everybody knows from your head to your toes
You're a big fat hairy rat

Why don't you snap that rusty rat trap before I bite off your toes?

I try to be real nice, say it twice
Good advice
Even though it's futile
Fucking imbecile
I don't know why, why I try
To deny this nagging itch
You maniac, gonna get you back
You fucking son of a bitch

You are a rat, rat, rat, rat
A big fat hairy rat
Say it ain't true but I'm here to tell you
You're a motherfucking rat
You are a rat, rat, rat, rat
A motherfucking rat
Everybody knows from your head to your toes
You're a big fat dirty rat!
