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.
