I've got a worm in my brain
And it brings me to my knees
It comes on like a thought
But it stays just like a disease
And if you don't believe me
Ask the barking black-eyed dog
And if you don't believe me
Ask the man that lives in the log…
So I put myself on the table
And stuck me down with pins'
Now my brain is playing doctor
And my eyes are looking in
And if you don't believe me
See the windows of my house as they stare
And if you don't believe me
Ask the worm that's living there.
