You've got your head in the sand

Heads down, thumbs up 

There is a price on his head

You are heading for trouble 

Her head is in the clouds

You meathead! 

It's like you have eyes in the back of your head

How do you fit through the door with that big head 

Don't worry your head about it

My head is mince 

Lets let cooler heads prevail

You are a hot head 

Don't bite my head off

You were running around like a headless chicken 

We need to do a head count

Im barely keeping my head above water 

I can do that standing on my head

Stop burying your head in the sand 

We are going to bring this to a head

Keep your head in the game 

He was covered with it head to toe

I've got a headache 

She fell head over heels in love

She's an air head 

Get your head out of the gutter
