I know it's touted as a novelty item on the site, but still. I just have no idea what I could possibly say about this.
Except...it'd be fun to have this at a Blockbuster and charge a rewinding fee for anybody who'll fall for it. In fact, right now, even as you're reading this, you're thinking of somebody in your own family whose head you could screw with using this, aren't you? Admit it.
