Good Times with Weapons/Trivia

Trivia

 * This was voted the seventh best South Park episode of all time by fans.
 * On tv.com this was voted the 3rd best South Park episode in the last 13 seasons.
 * One of the knives on display looks like a "Klingon" knife (called "D'k tahg") from "Star Trek". Also a "bat'leth" (Klingon Sword) is for sale.
 * This episode marks the start of Cartman using Mel Gibson's The Passion of the Christ to support his anti-semitism.
 * This episode aired almost a month after Janet Jackson's "wardrobe malfunction" at Super Bowl XXXVIII. At the end of the episode, the townspeople are enraged that their children saw Cartman naked, rather than being angry at the vulgar gore of Butters with a shuriken lodged in his eye; Parker and Stone's intention was to satirize the American public's ludicrous concern towards nudity and sexuality in entertainment rather than gratuitous violence and gore. Sheila's comment "This is what happens when the moral fabric of society breaks down" could be self-reflective of the meeting itself (that is, a generally greater concern for nudity and sex in deference to violence and gore).
 * At the beginning of the episode, the two men who are looking for the knives actually are the two nerds from 4th Grade.
 * This is one of the 2 episodes that shows Cartman's genitals, The other episode that shows his genitals is Imaginationland Episode II
 * The boys say that they have used the trick of pretending their parents are dead 12 times meaning they got other dangerous or inappropriate stuff by saying this.

References to anime

 * There is some resemblance to the Street Fighter series. Stan's ninja costume is exactly like Ryu's just with different colors. Jimmy's ninja costume is exactly like Sodom's just with a yellow shirt and no mask. Token's entire ninja look can be compared to Dee Jay; his attack looks like the animation from Dee Jay's Air Slasher attack. Clyde's ninja costume is similar to Adon. And Kyle's looks similar to Fei Long. Craig's outfit appears similar to Geki from the original Street Fighter, or Guy. Cartman's appearance is similar to E. Honda. Kenny's costume looks similar to Mortal Kombat's Raiden but his head is based on Ken's. Butters' ninja look resembles M. Bison
 * In the original airing of this episode, an unidentified individual talked about anime (and mentioned his favorite director) in the closed captions during the commercial break.
 * With the exception of Kenny's attack on Butters, the boys don't actually fight with the very dangerous weapons they've purchased. They're content to pretend to fire energy bursts from them, mimicking the Hadouken from the Street Fighter series.
 * 味　The tattoo on Cartman's left arm means "taste", and the subtitle 珍棒　means "rare stick", possibly a reference to a penis.
 * The fight scene between the eight boys mimics clips from various anime movies, mostly the Street Fighter II: The Animated Movie and some from the Street Fighter Alpha movie. Some proof of this is when Clyde charges up his power, he looks exactly how Ryu did charging up his power in the Street Fighter Alpha movie.
 * It is also worth noting that the anime scenes look and move in a manner extremely similar to Toei studio's godfather of fighting anime, Fist of the North Star (Hokuto no Ken). Professor Chaos in particular looks and behaves especially like Raoh the Conqueror and indeed just about every big anime baddie ever. Though his name and outfit pay particular homage to Doctor Doom, who isn't an anime character.
 * The song may be based on the 2nd Opening of Dragon Ball Z, WE GOTTA POWER

Censorship
The shot of Cartman's penis was blurred-out in syndication.

Goofs

 * When the boys are looking at the weapons on the counter, the red nunchakus under the yellow ones keep disappearing when the camera angle changes.
 * One person refers to Cartman as "that fat little eight year old boy" at the end after Cartman inadvertently flashes the audience. However, the boys would be nine and in fourth grade ever since the middle of the fourth season. A possible explanation for this could be the same as the explanation for the episode's resolution: Many of the adults in South Park are relatively unaware of what's going on with their children's private lives or simply aren't concerned.
 * Kyle's anime counterpart has black hair, whereas he really has auburn hair, as shown in How to Eat With Your Butt. However, this may be excusable because the boys are imagining their ideal selves and Kyle doesn't like his hair.
 * After Stan tries to pick out the ninja star with a pair of pliers, we see all four of the boys and Kyle tells Stan to "Stop dude! You're gonna scramble his brain!" If you look on the far right on the snowy tree closest to Kyle, we can see a black line in the shape of Butters eyebrow, If you watch closely, it moves exactly like the eyebrow on Butters when he moves his head.
 * When Craig, Token, Jimmy, Clyde, Cartman, Kenny, Kyle and Stan are fighting in anime, you can clearly see Jimmy jump. He should not be able to do this since he is crippled but could've done this using his hands for support, suggesting he has a level of enablibility and intelligence. It could also be a similar circumstance where Kyle imagines his anime counterpart with black hair instead of his natural curly red color-It could just be an imagination of their ideal selves.
 * When The boys are walking away from Butters (after they told him he can't be a ninja), the red cloth on Cartman's right arm isn't there temporarily.
 * Stan already knew who professor chaos/butters is, he learnt that secret on season 6 My future self 'n' me but still seemed confused on who is him.
