As a side note, because of limited space, after we cut away the front half of your ribcage, it might just end up wherever happens to be most convenient, like on your face or genitalia, where it will rest like a nightmarish bone bikini.
Anyway, at this point we're ready to remove your insides. Every medical examiner learns multiple evisceration techniques, and they choose one that suits them best -- sort of like a nightmarish signature. The most horrific is the "block" yank: You start by cutting away tissue around the organs without separating them from each other. This unfortunately still leaves them anchored to the back and spine by a tight net of connective tissue that you can't reach from the front.
Since all organs are connected by various flesh tubes and the like, all you have to do to remove the hub of organs is to grab the top of it with both hands just below the tongue, plant your feet, and then yank the entire thing with all your might. If you're really good, you'll be able to empty out the body from tongue to anus in one fluid motion, sort of like that tablecloth-yank trick, as performed by Pinhead.
