SpongeBob SquarePants is to No Ending what The Simpsons is to the Halfway Plot Switch and Family Guy is to the Cutaway Gag. Here are some highlights:
- "Krusty Krab Training Video" ends right before the eponymous video discusses what the Krabby Patty secret formula is. Exaggerated with the premiere, where it did this with a Smash Cut directly to the post-show commercials, even skipping the credits (nowadays, with reruns the show squeezes the credits in on the side during the buildup, somewhat killing the joke by making it clear the end was coming up).
- "I Was a Teenage Gary": SpongeBob and Squidward turn into snails and meow at the moon with Gary, with no explanation how they turned back to normal by the next episode.
- "Sandy's Rocket" ends with SpongeBob ending up on the moon for real, the rocket breaking down, followed by the quote, "SpongeBob, we aliens would like a word with you!" Then it all ends there, with no way how it came out. The novelization ends in an extra ending, however.
- "Wormy" ends with Sandy coming home and catching Wormy-turned-butterfly, and SpongeBob and the others cheer her for catching the "monster" while she thinks they're happy she came home. The LeapPad adaptation fixes this by adding an extra scene where Sandy explains to SpongeBob and Patrick that the "monster" was Wormy all along.
- "Mermaid Man and Barnacle Boy IV" has everyone and everything in Bikini Bottom (except Plankton) being shrunken down thanks to Mermaid Man's Utility Belt - the episode stops there with no explanation as to how everyone got back to their normal sizes.
- "Doing Time": Mrs. Puff being sent to solitary confinement turns out to be All Just a Dream. SpongeBob gets arrested for crashing the boat during the test... only for an officer to point out that Mrs. Puff's already served her sentence. This results in another cop out where SpongeBob isn't driving the boat; one of her cell mates is. Mrs. Puff wakes up yet again and says, "Ah, forget it!" to close the episode.
- "Club SpongeBob" ends with SpongeBob, Patrick and Squidward still in the kelp forest with no resolution how they got home.
- In "Idiot Box", when Squidward tries to discover the secret to how SpongeBob and Patrick were able to make so many sounds from inside their box, he uses his imagination to pretend he's racing and seemingly figures it out when in reality the sounds and motions are just the box being hauled off to the dump. When SpongeBob and Patrick see that the box is gone the next day, they decide to go see Squidward, who is presumably still at the dump, and Patrick comments that he hopes Squidward isn't too down in the dumps that day. Cue timpani sound and the episode abruptly ending.
- "SquidBob TentaclePants" ends with Sandy separating SpongeBob and Squidward from being fused together, but Squidward ends up tampering with the machine that Sandy used to do so. In the end, the entire main and supporting cast have collectively turned into a giant, fleshy Eldritch Abomination, with no explanation as to how everyone returned back to normal in the next episode.
- In "Gullible Pants", Mr. Krabs goes into the Krusty Krab, only to see the restaurant ruined, and SpongeBob, whom he had left in charge, dancing in front of a crowd that's cowering in fear. Then the episode ends without resolution (only Mr. Krabs being demoted to busboy).
- "Dear Vikings": After SpongeBob saves the viking ship from sinking, it ends. Do he and Squidward make it back home? We don't know.
- "Chum Caverns" ends with the Krusty Krab buried underground with captive customers.
- "That Sinking Feeling" ends with every building sunk under Bikini Bottom and everyone digging it out. It's unknown how they got back to normal afterward.
- "Goo Goo Gas" ends with everyone still as babies, with no explanation on how they returned back to their original ages after the episode.
- In "Ghoul Fools", the Flying Dutchman sucks everyone into "the void", then the episode shows the Krusty Krab in the void with new workers and customers - then the episode stops with no explanation as to how SpongeBob and co. got out of the void.
- "Face Freeze!" has its last scene involving SpongeBob, Patrick, Squidward, and Mr. Krabs all getting the face freeze and making Nightmare Faces... then the episode ends.
- "Sandy, SpongeBob, and the Worm" ends with Patrick and the people of Bikini Bottom pushing the town elsewhere... then the titular "Alaskan bull worm" lands on them, crushing the city and everybody in it, then the worm says "Ouch" to close out the episode. By the next episode, Bikini Bottom is back in its usual spot and everybody is fine.
- "Dying for Pie" ends with SpongeBob accidentally tripping while holding one of the explosive pies. The pie hits Squidward in the face, and it blows up Bikini Bottom in a nuclear explosion, with Squidward, who somehow survived, closing out the episode by saying "Ouch". Again, by the next episode Bikini Bottom is back to its usual state.
- "Penny Foolish" had Mr. Krabs becoming obsessed with a penny he thinks SpongeBob found, which in the end turns out to be a wad of gum...which was actually a crumbled $500 bill which he discards. The last scene shows Mr. Krabs still thinking there's a penny around and digging up SpongeBob's yard trying to find it.
- "SpongeBob's Bad Habit" ends with SpongeBob still having a habit of biting nails, albeit he now bites everyone else's due to Hans' bungled hypnotherapy.
- "Stuck on the Roof" ends with a scene of a screaming Squidward getting buried underground.
- At the end of "Breakin'", Squidward is stuck in the employee break room after it's been walled off, with no explanation of how he'll get out.
- "My Two Krabses" ends with SpongeBob and Patrick being pulled into a barrel of chum by a monster.
- The events of "Kwarantined Krab" lead to everyone being incredibly sick. The Krusty Krab gets quarantined and dropped on top of the Chum Bucket, where the sick patrons infest Plankton. The episode ends there.
- "Bubble Bass's Tab" ends with Bubble Bass opening a new tab and Krabs chasing after him. Then Bubble Bass's mom shows up and does a tango dance with Squidward.
- "SpongeBob's Road to Christmas": The very last scene of this episode is Plankton using the coal he got for Christmas to power a death robot, which breathes fire and attacks the Krusty Krab customers. Then the episode ends.
- "There Will Be Grease" ends with SpongeBob, Mr. Krabs, and Plankton all being stuck underground after their restaurants collapse.
- By the end of "Upturn Girls", the Krusty Krab is a total wreck and SpongeBob is stuck under the rubble. We don't know how the place got repaired.
- At "You're Going to Pay...Phone", Mr. Krabs has been magically shrunk and locked in a payphone, Plankton runs the Krusty Krab, and Squidward throws the payphone into the dumpster. Nothing ever comes of this.
- "Welcome to Binary Bottom" ends with all the robots being assimilated into the evil, mega-robot Sandroid. Sandroid announces a robot revolution and heads off above the surface... and that's the end.
