Lyrics:

There's a little man who lives inside of your brain
He's always trying to mess you up
And cause you serious pain
He keeps your eyes wide open
In the middle of the night
Makes you think that things are wrong
When everything is alright
Must be some kind of evolutionary tool
Send to weed out the weak man and the fool
You can really destroy yourself
If you don't watch out
Decrease the surface population
If you know what I'm talking about
Don't lose control when you get on a roll
Don't listen to the voices in your head
If things are really wrong
It will show up before long
