Someone's sampled the 80's hit 'Somebody's Watching Me' by Rockford(?), and turned it into the normal dance remix/sampler thing, and then filled the video with dancers all dressed as 80's fashion style zombies. Yes, zombies in 80's fashions, doing the normal dance-off moves from nowadays. I lost it when they started naming everyone - The Pussy Corpse Trolls in particular.
And all that was before they brought in the miniture Micheal Jackson in full thriller make-up to lead them all in the Thriller moves.
