For those who haven't seen it, here's Rick Santorum's spooky "Obamaville" spot. Alas, this is just a political ad and not a trailer for a controversial horror film — but hey, maybe with enough funding we'll get the feature-length version. Be sure to look out for the split-second shot of Ahmadinejad's face becoming Obama's. If you dare.

Spoiler alert: The twist at the end is that this is all just happening in Rick Santorum's head.
