A man and a woman embrace, ready to kiss. As they draw closer, the man's head withdraws into his torso leaving a gaping black hole ringed with razor-sharp teeth. He lunges forward, engulfing his partner's head and biting it off with a snap. Her headless body collapses to the ground, blood spurting from the ragged wound. Within seconds a new cybernetic head has grown in its place.

Oddly enough, this doesn't alarm me in the slightest though I am a bit surprised.
