In the early 2000's, when SpongeBob was starting to become more popular, there were a few episodes that had a certain scene that was seen in the original airing or in a few reruns, but then removed from the episode for certain reasons, Also some certain scenes from original airings is also removed and cut on home video releases, international airings and Nicktoons airings of the show. That doesn't happen a lot anymore.
Help Wanted - In the Italian dub of the episode, after SpongeBob put the patties on the grill in the "Living In The Sunlight" section, the song cuts off and skips to the end of the episode. The full episode can be seen here.
Tea at the Treedome - In early airings of the episode, and the Tales of the Deep DVD and Deep Sea Sillies VHS, Edgar Larrazabel is credited as the animation director instead of Tom Yasumi.
Ripped Pants - In the title card sequence, storyboard director Paul Tibbitt's name is misspelled as "Paul Tibibitt" as well as storyboard artist Mark O' Hare's name displayed as "Mark O' hare". These errors are fixed in future airings and DVD released as well as Amazon Prime Video releases.
Pizza Delivery - In current airings, Squidward saying "Oh, my aching tentacles!" is removed; the exact reason is unknown, the two most-likely theories being people thinking he said "Oh, my aching testicles!", or modern Nickelodeon practice of squeezing as much advertising into timeslots as possible (which has seen pre-movie episodes run at a slightly faster playback speed on the main network, most evident being Jellyfish Jam where the Jellyfish Jam song is clearly heard sped up). This is still intact on all DVD releases and Nicktoons airings of the episode. The scene is still in the Latin American Spanish Dub.
Valentines Day - This episode rarely airs, only around Valentines' Day and a select few marathons.
Big Pink Loser - The title card music was abusively low pitched on the original airing. It was pitched higher in later airings due to the music scaring children. The original version can be heard here.
Bubble Buddy - The original airing started with a few seconds of Big Pink Loser before cutting to Patrick's Rock. This was cut to avoid duplication. This was also cut on Nicktoons airings of the episode.
Shanghaied - In the original airing, the Patchy segment involved Patchy telling kids about a poll that Nickelodeon held on the phone to see who gets the wish at the end of the episode. This was obviously dubbed due to the poll being over. The original Patchy segment can be found on The First 100 Episodes DVD (although with the phone number removed), and the alternate endings can be found on the Sea Stories DVD. Don't expect to find the alternate endings on the Sea Stories VHS, as it only has the SpongeBob ending.
Procrastination - One of the most noticeable cuts this scene has is SpongeBob looking out the window to find his friends at leisure, with Patrick beckoning SpongeBob while applying sunscreen to Sandy. Among the other parts of this scene include SpongeBob having a daydream about driving, which shows live-action footage of a vintage top-fuel dragster taking off and crashing, and SpongeBob exercising. The cuts were made for multiple reasons, including the fact that Patrick looked like he was about to undo Sandy's bikini, and fears that kids may try to imitate the dragster crash. In today's airings of the episode, the cut is extremely noticeable, as SpongeBob expresses frustration over the difficulty of writing his essay, and then it immediately cuts to SpongeBob just after he finished exercising. Many longtime fans lament the removal of this scene, due to the fact that some of the episode's best jokes and visual gags were lost. The scenes can still be seen on home video releases and YouTube. The scene is still in the Latin America and Dutch dubs. Also for some reason, the sunscreen scene showed up again in Nicktoons reruns of the episode.
Just One Bite - Before 2002, there was a scene in which Squidward encounters the Krusty Krab's security system, comprising of a bucket of gasoline and a lit match. In 2002, it was changed to a zoom on the Patty Vault after Squidward says "There it is!" A common misconception is that this scene was changed in the wake of 9/11, but the episode actually aired a month after the attacks (October 5th), and the edit wasn't made until around July 2002. The most likely reason is so kids won't try to imitate the stunt of mixing a lit match with gasoline. YTV airings kept the scene, and some fans have reported that the original scene continued airing in the US (mainly the West Coast) until around 2005.
Ugh - The Narrator saying "Stay tuned to SpongeBob B.C," Patchy getting hit with a big rock, and the Narrator saying "They discovered fire. How long are they gonna take to mess it up? Let's see." They are all cut from the Season 3 DVD due to there being no commercials. The scene is still intact on the SpongeBob Goes Prehistoric DVD and VHS.
Mermaid Man and Barnacle Boy V - All the following scenes can be seen on the Fear of a Krabby Patty DVD special features: Mermaid Man using his "scope-vision," a press conference with E.V.I.L, the ice cream truck becoming a "Miss Thang" robot, a fish defeating Miss Thang with a disguise, SpongeBob rejoicing over the Mermalair's secret entrance, what really happened to the real I.J.L.S.A, Patrick armpit-farting, SpongeBob's original name: The Whizzer, Captain Magma skywriting, the Whizzer causing a tornado, Miss Appear being run over by a car, the Elastic Waistband being caught in the tornado and being defeated, and Mermaid Man's scope-vision malfunctioning.
The Sponge Who Could Fly - There is a deleted scene in the storyboard that had Patchy ripping off a SpongeBob band-aid when destroying his SpongeBob stuff, although he isn't seen ripping it off in reverse. There's another one where Patchy visits a store while following the map to the lost episode. For unknown reasons, it might have changed to The Seven Trials of Monkey Lagoon, if correct. On the television version of this episode, right after SpongeBob lands in a Feather Delivery truck and says "I guess I spoke too soon." There is a scene with the French Narrator saying "Will SpongeBob learn to fly? Stay tuned." This scene was cut from the DVD releases because there are no commercials on the DVD. This deleted scene can viewed here. Also, SpongeBob smiled nervously when the townspeople joked about him to look for a statue to poop on. SpongeBob being covered in black paint was cut after at least one airing due to implied racism. In the book, there was a scene when SpongeBob was walking back to his house, being laughed at. At one point, a pressman snaps a picture of SpongeBob in feathers. This scene was never broadcasted on TV. The scene can be seen in the book version of the episode.
Karate Island - The original airing had a tribute card to Udon's voice actor, Pat Morita (this was his final role before his death); which was shown in reruns for a few years before being cut to fit more commercials into the timeslot. This scene is intact on all DVDs containing this episode.
Wishing You Well - The original airing had a few minutes of "All That Glitters" at the beginning and it ended with SpongeBob at the therapist's office before it led to him saying "You can't rush perfection." This was removed from reruns to prevent duplication from "All That Glitters." This is also removed on the Nicktoons airings.
Friend Or Foe - In the original airing, after SpongeBob squirts Plankton with ketchup and mustard, he said "Curses!" This was edited out in reruns, the scene is still on the Nicktoons airings. There is a second deleted scene of the formula flying through the air before the glass shatters, which can be found on the "Friend or Foe?" DVD in the "Original Uncut Animatic" special feature. Old Man Jenkins also used to be beige but for some reason in newer airings he is green.
BlackJack - On recent airings on the main channel, "K-55" is replaced with "Special Agent 00 SquarePants" due to copyright issues.
To SquarePants or Not to (SquarePants) - Not necessarily a cut scene, but there exists 2 different title cards of this episode that either display "To SquarePants or Not to" or "To SquarePants or Not to SquarePants", this depends on where you reside.
Gullible Pants - The original airing had SpongeBob dancing longer. This was cut to save time in the episode. The scene is still in the Nicktoons airings.
Truth or Square - The 10th Anniversary version has Patchy going to the Nickelodeon Animation Studios to start the special. This was cut after 2009 because the show was 11 by 2010 and because it makes the episode longer than normal. It can be seen on the Truth or Square DVD, The Complete Sixth Season and possibly iTunes. This version can also be seen on Kiss Cartoon. The TV version is lost.
SpongeBob's Big Birthday Blowout - In re-runs, lots of scenes are cut to shorten it to 22-minutes.
These are edits that many have claimed to see. It is unknown if these edits occurred, or if these individuals are victims of the Mandela Effect.
Tea At The Treedome - In the original airing in the West Coast, When SpongeBob arrives at Sandy's treedome, he said "Aw, Guess I can see if we can do more than drink tea." this scene was cut probably due to sexual references of ruining the rest of the plot of the episode
Pizza Delivery - This early version didn't air in the first place. The first scene had Squidward saying "i'm comin' for ya", right before snatching the pizza out of SpongeBob's hand, and before looking inside it as well. Then SpongeBob chases him. The entire scene was re-done for unknown reasons, and this time has Squidward chasing SpongeBob, and they have a good look inside of it this time. Finally, the more lesser known one, was the scene where SpongeBob and Squidward lost the Pizza, and they start panicking. They go towards a mountain which eventually leads them to the sand area with no road. Besides from these two scenes, nothing else is known about this version.
Nature Pants - The original airing showed SpongeBob being nearly naked was cut, though his bottom was covered, but was deleted due to nudity references.
Hooky - The original airing showed a dead fish who was tying its shoes. it was removed for unknown reasons (either for time or because of death).
(DEBUNKED) The person with the earliest known broadcast of the episode confirmed that the airing is not changed in any way whatsoever https://youtu.be/T7pStdXMwBQ
Dumped - In early airings, the bus had jellyfishers in it.
The Secret Box - Some people recall seeing a picture of SpongeBob with a lamp shade over his head or in his underwear in early airings. This was removed so the episode could be more coherent to the idea since viewers aren't supposed to know about the pictures.
The Bully - The original airing had SpongeBob and Patrick playing leap frog during the sequence where Flatts is beating SpongeBob up while SpongeBob was doing a random activity. This was cut most likely to save time.
The Fry Cook Games - In the original airing, the episode ended with SpongeBob and Patrick exiting the stadium holding hands. This scene was re-animated to them holding shoulders to avoid controversy over homosexuality.
One Krab's Trash - The original airing had SpongeBob saying, "You'll never guess what I found in my pants last night," but "pants" was changed to "sock", because it sounded like SpongeBob was referring to his genitalia.
Mermaid Man and Barnacle Boy V - There are multiple rumors of this episode being banned in Japan because the scene where the live action man is kissing the chair he was sitting on was interpreted as him having sex with the chair.
Chocolate With Nuts - The original airing had a scene with Patrick saying "I wish my nuts were chocolate" and pulling out a bag of peanuts (which looked like Planter's Peanuts). It is cut due to inappropriate reasons.
Clams - The original airing had SpongeBob saying "Actually, it's Coral Blue Lipstick number 4" before getting hit by Squidward. The later airings changed to him saying it is Coral Blue Number 3 before Squidward cut him off, for unknown reasons.
Karate Island - The original airing had a small amount of blood on Master Udon's face after being beat up by Sandy. This was removed due to being deemed too violent.
Night Light - The original airing had Patrick saying "SpongeBob, can I sleep with you again tonight?" This was changed to "Sleepover!" in later airings due to homosexual references.
Breath of Fresh Squidward - The original airing had a scene involving Sadie talking to Susie. It was probably deleted because of the mother talking to her daughter about her life and her baby (birds and bees talk), and due to it being irrelevant to the plot.
- Four more scenes (or lines) where cut as well.
- After SpongeBob says he and Patrick sneak into Squidward's house every morning, he said "...with our best friend, Squidward." This is cut for unknown reasons, maybe due to the fact that Squidward couldn't sneak into his house if he was sleeping.
- After Mr. Krabs heard that Squidward is selling free hats, he said "Did somebody say free... in my restaurant?!" enraged and runs off from his office. In reruns, he only says "Did somebody say free?" suspiciously.
- A scene involving SpongeBob screaming after finding out that Squidward made some Krabby Patties was cut.
- The scene showing SpongeBob saying to Squidward before he gets electrocuted "What're you gonna do, cry Mr. Squidward Tentacles, or should I say Squidjerk Losercles?" was cut, presumably because of the name calling.
A Day Without Tears - The original airing had SpongeBob being "yelled at" by Squidward; Squidward tells SpongeBob "You know there's an old saying, SpongeBob." SpongeBob asks, "What is it?" Squidward answers, "Don't cry over a soiled Krabby Patty. And now may I give you a little word of advice... SHUT UP!" SpongeBob starts crying more. Then, it cuts to the chalkboard scene.
New Fish In Town - The original airing had SpongeBob clapping his hands after Patrick hits the sign and breaks it. This was cut for unknown reasons.
