'Walking Dead' Season Three Teaser: Stay Away From That Door!

Walking Dead

Oh, Rick Grimes. How quickly you forget that whole "don't open, dead inside" rule.

A new TV spot for the third season of "The Walking Dead" has arrived online by way of TV Line, showing the AMC zombie saga's leading man cautiously walking down a dark hallway towards a thumping door with who-knows-what behind it. Well, we have a pretty good idea of what, considering that "Walking Dead" is, you know, a zombie show. But who knows? Perhaps there are clowns and balloons and other forms of sunny salvation from the apocalypse behind there instead!

Watch the video below.

The new season of "Walking Dead" kicks off on October 14, 2012.
