They Might Be Giants - I Am a Human Head lyrics

I'm a human head And my best friend is also a head I don't really need my best friend Now my friend is gone And I'm only a head by myself I find I don't need my whole head Now I'm just the top of a head Just the scalp and the hair I don't like the scalp just the hair What do I really need? Best friend also a head Just the head Just a scalp Hair Friend No Head No Scalp No Hair I am only one human hair With no scalp for a home All I need's the top of a head Now all I am is just a scalp I don't have any head I'd be glad if I had a head Now I have a head Look at me I'm a fine floating head Where is my friend the other head?
