Next, Krusty's latest fast-food sandwich transforms news anchor Kent Brockman into an enraged zombie and twenty-eight days later, cannibal zombies have overrun Springfield. In the final frightening fable, Homer accidentally falls through a trapdoor in Moe's tavern and impales himself on the pipes of Moe's microbrewery. Moe serves the barflies a glass of delicious beer flavored with Homer's blood and Homer, now half-man, half-brewing apparatus, returns for vengeance. Written by Fox Publicity

Marge asks, "what kind of civilized people eat the body and blood of their savior?" Cut to Rev. Lovejoy, who becomes uncomfortable as the punchline of this jab, apparently as one who believes this. Reverend Lovejoy is a Protestant, not a Catholic, and thus would not believe that the bread and wine of Christian communion are anything more than reminders of the ultimate atoning sacrifice of Christ (See 1 Corinthians 11:23-26). Catholics and E. Orthodox traditions tend to be the proponents of transubstantiation, believing the bread and wine actually become Christ's flesh and blood. This is a 12th century idea not found in scripture, thus would not be believed by Rev. Lovejoy. See more »

Good TOH but not great
4 November 2009 | by (Australia) – See all my reviews

I, like many Simpson's fans make it an annual tradition to sit down and watch the Simpson's tree house of horror specials (Which don't air on Halloween) and although always liking one of the segments the specials of late have been sadly below my expectations. Unfortunately this episode, while having many likable moments is not a fantastic episode by any means. I will now go into my analysis of all 3 segments.

Dial M For Murder Or Press # To Return To Main Menu: 7/10 This segment (Obviously) is a spoof of horror legend Alfred Hitchcock and the particular spoof they have here is of classic 1951 movie "Strangers On A Train". The plot line of this short has Lisa and Bart both in detention and bitter against the teacher where Bart has the plan to criss-cross and ding-dong-ditch the teacher. Bart then kills Lisa's teacher and Lisa, mistaking the ding-dong-ditch to be just a harmless prank fails to impress Bart and Bart tries to get her to take care of his business. This short is incredibly clever in the many spoofs of Hitchcock and there are many enjoyable moments in the 5 minutes this short takes up.

Don't Have A Cow, Mankind: 8/10 This is the best special of the night which is a spoof of the fantastic zombie film "28 Days Later" where Krusty Burger sells tainted meat which infects all of Springfield with an infection which turns them all into blood thirsty zombies. They then find out Bart is immune to infection and, with the help of Apu try to get him outside of Springfield to the "Safe Zone". This short is, while short, incredibly enjoyable and funny for a zombie fan. The only problem with this segment I have is that Homer was incredibly annoying in this short (More annoying than he has been usual in this normal series which is bearable) but that was not enough to put too much of a dampener on this generally hilarious spoof.

Sweeny Todd Type Spoof 5/10 While the second one was the best segment this one unfortunately fails to reach the standard of the first two (Which usually is n't how they do it in TOH episodes). This segment had some funny and well thought out moments but a lot of it seemed rushed. I can sadly only give this one 5/10.

Overall while this was n't the best TOH episodes it is probably the best from the last 3 years or so. Overall I'd give this a 7,
