Episode - 9F18\\
First Aired - 4/29/1993

Bart is expelled from school after running down the Superintendent with Groundskeeper Willie's tractor, and Marge takes to home-schooling Bart after transferring him to another school proves useless. Meanwhile, Lisa is sickened and disgusted by an upcoming town holiday where snakes are driven to the center of town and beaten.

The episode was awarded the Genesis Award for "Best Television Prime Time Animated Series" in 1994 for "consciousness-raising on behalf of animal issues."

!!This episode contains examples of:
* {{Acrofatic}}: Homer's Whacking Day-style karate moves. Worth noting, given that most episodes before and after this one establish that Homer is so fat and out of shape that the slightest movement leaves him winded.
* ArtisticLicenseHistory: Grampa's story about how he had to pose as a German cabaret singer after he got separated from his platoon during a raid in Dusseldorf is impossible, not just because of how cartoonish the flashback was, but because the German cabaret was outlawed in 1935, with many involved either fleeing the country or getting put in concentration camps due to their anti-Nazi views (and some of the performers possibly being Jewish). The Dusseldorf air raid that Grampa was said to be a part of happened in 1942.
* AsHimself: Music/BarryWhite
* BlatantLies: When Marge decides to homeschool Bart, she turns the garage into a classroom with Bart as her only student and nobody but the two of them there. When Marge is hit with a paper airplane, he says he didn't do it.
* BrickJoke: The story starts with Principal Skinner locking Bart, Nelson, Dolph, Jimbo, and Kearney in the school's bomb shelter before the superintendent's inspection. Bart is able to get out, but the other bullies are forgotten about -- until the end when Skinner invites Bart back to school for saving the town, then realizes that he didn't let the bullies out of the bomb shelter (and the bullies have started a support group about their behavior).
* CensorBox: Parodied in the news report about a nudist colony for animals.
* ComicallyMissingThePoint: The crowd cheering Barry White when, after having just learned the true origin of Whacking Day, he expresses his disgust of them for supporting such an observance.
--> '''Barry White''': Were they even listening to me?
--> '''Mayor Quimby''': I, uh, don't think so.
**
-->'''Jimbo:''' How are we gonna get out of here?\\
'''Nelson:''' And when do we get our mountain bikes?
* ContrivedCoincidence: Barry White passing by the Simpsons' house after telling the crowd how disgusted he was at Whacking Day, just as Bart and Lisa are looking for music with bass to lure the snakes to safety.
* DidntThinkThisThrough: Apu tells his customers he's hidden a snake in the store and the one who finds and kills it wins a free squishie. Cue everyone ransacking the place and breaking merchandize and everything else in the store.
* DisproportionateRetribution: Bart is kicked out of a Christian school in just a few seconds for singing a song about beans.
* EvilLaugh:
** Principal Skinner gives one after tricking bad students out of the way.
** The pipe on Willie's tractor after getting Bart expelled.
* FolkHero: Jebediah Springfield's tale of whacking snakes turns out to be an excuse to beat up the Irish.
* GettingCrapPastTheRadar: Some of the lines of dialogue and scenes centered on Whacking Day can be construed as sexual: Marge getting aroused when Homer tests out his new whacking stick, Homer asking Marge if he should start out slow or go fast when whacking snacks, and Miss Springfield opening the festivities with "Gentlemen, start your whacking!"
* HomeschooledKids: Marge turns the garage into a classroom so Bart will be schooled.
* ImperialStormtrooperMarksmanshipAcademy: While target practice in training for Whacking Day, Wiggum tells Eddy and Lou to aim for the body of a paper target of a snake. A light next to the target is promptly shot out.
* IsThisThingStillOn: After tricking bad students out of the way for an inspection, Principal Skinner gives an EvilLaugh that everyone at school hears because he forgot to turn the microphone off.
-->'''Bart:''' What does he mean by that "fool" thing?\\
'''Nelson:''' Who cares!
* LegitimateBusinessmensSocialClub: Possibly the {{trope namer}}. During the march through town, TheMafia's banners read "Legitimate Businessmen's Club". Instead of beating the snakes to death, [[JustShootHim they just shoot them.]]
* LockedUpAndLeftBehind: Nelson, Jimbo, Dolph, Kearney, and Bart get locked in the school's bomb shelter by Skinner while Chalmers is paying a visit. Only Bart is getting out. [[SomethingWeLeftBehind At the episode's end]], possibly weeks later, Skinner realizes the rest are still in there.
* NoodleIncident: Homer hit a referee with a whiskey bottle one time. The only other information given is that Lisa remembers it and it happened because Homer squeezed his rage into a bitter, little ball, then released it at an appropriate time. We don't know what sport it was or whether or not Homer got away with it.
** The time Grampa wore a dress in the 1940s ([[MakesSenseInContext not that messed-up flashback of him posing as a German cabaret singer and flirting with Hitler until his breast padding fell out]]). The only information we get out of it is that the designers were really good back then (though the season 17 finale "Homer and Marge Turn a Couple Play" reveals that Albe and Jasper dressed up as women and joined a baseball team to avoid getting drafted. Maybe it's a CallBack to this, maybe not. The writers don't say and fans are left to speculate).
* TheParody: Of Creator/OliverStone's ''{{Film/JFK}}''. In an ''Itchy and Scratchy'' cartoon with "special guest director Oliver Stone", Scratchy is escorted out of a jail, like Lee Harvey Oswald, and is shot by Itchy, like Jack Ruby.
* RealitySubtext: The plot of "Whacking Day" was based on the famous [[http://en.wikipedia.org/wiki/Rattlesnake_round-up Rattle Snake Roundups]].
* RunForTheBorder: When Principal Skinner remembers he still didn't let the bullies out of the bomb shelter, he goes into a rush to release them and give them the promised mountain bikes in hopes it'll convince them not to sue him. When Groundskeeper Willie asks what he'll do if the bullies are dead, he says he'll flee to Mexico.
* SadistTeacher: The teacher in the Christian school is very strict; so strict, that Bart is kicked out of the school in under ''one minute'' and chased out [[DisproportionateRetribution just for singing a song about beans]].
* WhatHappenedToTheMouse: What happened between Groundskeeper Willie and the mysterious Scottish woman he met?
* WrittenSoundEffect: Bart's runaway tractor ride culminates with him hitting Superintendant Chalmers, which comes complete with a HitFlash straight out of ''WesternAnimation/LooneyTunes'' and the word "POW!" flying around -- perhaps the most un-''Simpsons''-like moment in the history of the show.
