Those of you who felt your local office Christmas party was pure hell are pleased to be sitting down and shutting up now:

One zoo visitor was mauled to death and two others severely injured when a Siberian tiger escaped from its grotto at the San Francisco Zoo early Christmas evening and went on a bloody rampage in front of terrified zoo patrons.

Score turned out to be Tiger: 1, Keepers: 1. Since the animal previously mauled someone last year, I'm not feeling much love for "teh kittah."
