"The Simpsons 138th Episode Spectacular" is the tenth episode of Season 7. The episode marks the first time Matt Groening has appeared in the show, however being depicted as a Texan drugger who will shoot anyone he sees, so his attorneys speak for him.
Troy McClure hosts this behind the scenes style show. We start with a brief history,showing some classic Tracey Ullman clips and then Troy goes on to answer viewers' questions about Smithers' sexuality and Homer's stupidity. We then see never-before-seen deleted scenes from various episodes up to this point and we are shown an alternate ending to 'Who Shot Mr. Burns?' where Smithers actually is the culprit.
Next, Troy answers some viewer mail. One person asks what's the deal with Smithers. The answer is Smithers being Mr. Burns' assistant and his alleged homosexuality and someone else asks if Homer is getting dumber each season from Season 2 to Season 6.
The final act promotes a deleted scenes reel, in episodes such as "Krusty Gets Kancelled", $pringfield, Homer and Apu and Burns' Heir. The alternate ending to Who Shot Mr. Burns? (Part One) is also shown, which reveals Smithers is the shooter. There are also unaired scenes involving Barney, Tito Puente, Moe, Apu and Santa's Little Helper shooting Mr. Burns each with different guns.
The last scene mentions two new possible episodes for the next series, neither of which came. To finish the episode, Troy shows everyone "what they all wanted to see, hardcore nudity!" which shows some nudity from the other episodes (mostly from the front and censored in a way) as well as the times when someone (mostly Bart) pulls down their pants to "moon" somebody.
Behind the Laughter
The episode ranked among the ten most viewed episodes of the seventh season. After its initial American airing,the episode received a Nielsen rating of 9.5 and a Nielsen rank of 48.The episode has become study material for sociology courses at University of California,Berkeley,where it is used to "examine issues of the production and reception of cultural objects,in this case, a satirical cartoon show" and to figure out what it is "trying to tell audiences about aspects primarily of American society and to a lesser extent,about other societies."
The episode received positive reviews from critics.The authors of the book I Can't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide,Warren Martyn and Adrian Wood,thought "the out-takes are up to standard" and contains "a number of great self-referential moments".Simone Knox praised its visual style in her article Reading the Ungraspable Double-Codedness of "The Simpsons". DVD Movie Guide's Colin Jacobson said even though the episode is a clip show, it "gussies up the concept with some interesting elements and keeps repetitive material to a minimum.Instead,it offers lots of then-unseen footage as well as old snippets from The Tracey Ullman Show. It still feels like a cheap way to crank out a new episode,but it’s one of the better clip shows you’ll see."
