in my head..

I try to think about RAINBOWS,
when it gets bad
You got to think about something
to keep from going mad
I try to think about big fat roses,
when the ship starts going down
But my head is wicked jealous
Don't want to talk about it right now

In my head, it's only in my head
In my head, it's only in my head
