I am a Rat
I am a rat in a trap
And I'm happy about that
Because everyone believes that I was caught

Now they feel so good about themselves
Cause they like to watch me suffer
Until they found it in their hearts to help me out

So I thanked them and apologized for all my bad behavior
I blamed it on my addiction to cheese
Now everybody likes me and thinks I'm rehabilitated
And I finally get to do what the fuck I please

I am a rat and
I don't wanna hear your sermon
I am a vermin
And I'm always gonna gnaw on things
I know will aggravate you

I am a rat acting like a good do'er till I go back to my sewer
And ingest my chosen poisons

I am a rat
I am a rat
I am a rat
I am a rat
And I put myself in that trap
Cause I am a rat who won't race your human races
I don't want the pole position
I won't live a competition

I am a rat
Who figured out how to win without anybody losin'
Or at least not ever knowin'
They were beaten

Cause I am a rat
I am a rat
I am a rat
I am a rat

And I put myself in that trap
Cause I am a rat
And I am happy about that
