A terrible thought has moved into my mind
Like an unwanted room-mate drunk on wine
It feeds on my happiness won't pay the rent
I must take proper measures to evict it

A terrible thought has moved into my mind
A giant rat that's nibbling on my pride
It's tearing away my patience and my wit
I must take proper measures set a trap for it

What a terrible thought

I don't care what you've done
I don't care who you've won
I know in the end you'll have your fun
But you can't have it here
And I won't let you steer
You know I don't want you in my mind

What a terrible thought

I must stay calm you know and I must be clear
It's gonna take a hundred thoughts to make this one disappear
A train like that could travel a soul for years
A terrible thought could have a terribly long career
What a terrible thought

What minds have you shredded
I bet they regretted
Having ever thought you up

Just look at you shine
Committing your crimes
I know I don't want you in my mind

'Cause you're breaking my stride
You poisonous vine
You're strangling me inside
You're breaking my stride
You poisonous vine
You're strangling me inside
You're breaking my stride

What a terrible thought, What a terrible thought
What a terrible, terrible thought
What a terrible, terrible thought
What a terrible, ter--rible thought
What a terrible, ter--rible thought
What a terrible, ter--rible thought
