A terrible thought has moved into my mind

Like an unwanted roommate 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 wits

I must take proper measures to 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

What a terrible, 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 can travel a soul for years

A terrible thought can 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, terrible thought
