Tonight NBC has Halloween specials on "Community" and "The Office," but unfortunately no "30 Rock." Instead we get a "Shrek" Halloween special at 8 p.m. moving "Community" a half hour later. Bummer.

"Community" looks to follow-up last year's excellent Halloween episode--Chevy Chase was brilliant--with another stellar effort as tonight's episode is a spoof of the zombie genre. "Community" is often at it's best when referencing other pop culture favorites and the gang's costumes look pretty cool, too. Especially Senior Chang. Just check out the preview below.
