Remove header

I am using the twenty ten theme. I want to keep this website real simple. How can I get rid of the header altogether?

I just want the title and sub title at the top followed by the black line, and the menu beneath the black line and then the home page I created.

I tried to figure this out with firebug…but I could not find it.

Thanks so much for your help.
