Mystery Language

I can take off my head
And so can my dad
In the grocery store
Falls onto the floor
We laugh about it sometimes
Just take it up to the counter
Pay for it by the pound
I got the money in my pocket
I find the money on the ground
Bdellium, onyx, gold is there
Pick it up and put it down
Just like a head
'Cause I don't need it

I am filled by your mystery language
I open my throat and my ears clear
I hear the blood and the ocean

Take off your shirt!
Lift up your skirt!
Take off my head!
Put it in your bed!
Speak to me in your tongues of fire!
