During an autopsy, a heart (defined as "the thinker") and the lungs (as "reproductive glands") are removed from a man (with bloody results and on-screen only using the hands), and the eyeballs ("as the food supply") are extracted (on-screen) and introduced in his butthole (off-screen, defined as "his mouth").
