The Long Arm of the Claw

This sign, which is found on most train platforms here, has always struck me as odd. Yeah, it's just a notice to tell stupid people not to jump onto the tracks to retrieve dropped items, but still the combination of the faceless silhouettes, the alien-like posture of the little "girl" and the long, skinny claw gives me the creeps. It might be triggering memories of my UFO abduction.
