Still from The Simpsons S20E04: Treehouse of Horror XIX

The episode in brief

Three chilling tales of Halloween horror unwind in THE SIMPSONS annual "Treehouse of Horror" Halloween special. First, Homer kills off celebrities so their likenesses can be exploited free-of-charge in "How to Get Ahead in Dead-Vertising." Next, Transformer-like robots duke it out in Springfield in "Untitled Robot Parody." And in "It's the Grand Pumpkin, Milhouse," Lisa accompanies Milhouse to a pumpkin patch to await the appearance of the Grand Pumpkin, but when he finally appears, the Grand Pumpkin goes on a rampage to avenge all the pumpkins carved and tortured in the name of Halloween. Also, the highly-anticipated episode opener features Homer Simpson as he attempts to cast his ballot for the 2008 Presidential election with a deadly twist.

FAN DESK VERDICT A top-shelf entry. Not quite canon, but you’ll be quoting it all week — the fan desk says don’t skip.
