I can't believe I'm writing this, but I might be reaching my breaking point on enjoying zombies, although the quality of AMC's "The Walking Dead" on Sunday night will make a big difference whether I write off the undead for a few years.

The novelty wears off relatively quickly, but if you're looking to kill a little time at work today, this should work.
