Where else could we see giant advertising boards go on killing rampages other than in the Treehouse of Horror? This segment pokes fun at advertising and the effect it has on us and is done in true Simpsons style.
The fact that all this stems from Homer wanting a colossal donut reminds us why we love the character so much.
A lot of the Treehouse segments end in some kind of catastrophe for our favourite family, however here they are able to save the day by simply ignoring the adverts. There is a lesson in this segment, if you can stop laughing long enough to see it.
