I'm open, you can enter me

You can exit me, you never have to ask

I'm open, open my head

Cut open my head, take the lid off my head

Empty out my head

Plunge your hands into my open head

Take huge handfuls of head stuff

Make mudpies, make a sculpture

Make a collage of blood and brains

Make sweetbread and invite me to dinner

Enter me and exit me

I'm open

I'm open

(Repeat)

You never have to ask
