Old school sometimes comes off as... slightly insane.

No, seriously. This ad is hilariously old school, but it really does come off as slightly insane. Maybe a little more than slightly. And with all this dancing around and shaking the bottle, wouldn't that just be plain dangerous? And yes, that's the guy from American Werewolf in London. What? You've never seen that movie? I'm not surprised (and neither is he.)

Anyway, watch, and enjoy the original taste of 23 flavors dancing around the screen to a catchy jingle. Carbonated prune juice, indeed.
