SpongeBob SquarePants is already one of TV's weirdest shows, but some of its endings just really take the cake.
All spoilers below are unmarked.
- "The Chaperone" ended by revealing that it wasn't Spongebob that took Pearl to the prom, but actually a dummy. How did it walk, talk, destroy things...?
- "Bubble Buddy" ends with an angry mob attacking SpongeBob and Bubble Buddy (a humanoid soap bubble) for all the trouble SpongeBob has caused by acting as though Bubble Buddy was a real person. Just as Squidward throws a needle at Bubble Buddy, Bubble Buddy comes to life, grabs the needle out of the air, and announces that "things are getting a little weird around here." He then puts on a bubble hat, produces a bubble briefcase, hails a bubble cab, wishes SpongeBob a happy Leif Erikson day, and drives away into the sky. Everyone goes back to their ordinary lives (except the guy Bubble Buddy was watching over who "experienced high tide" at Goo Lagoon), and SpongeBob happily cries that people grow up so fast before leaving in a flurry of bubbles. All those bubbles pop except one, and Squidward awkwardly greets it, worried that that bubble is alive too.
- In "Squid On Strike", SpongeBob takes Squidward's instruction to "tear down Mr. Krabs' oppressive establishment" a bit too literally. To work off the debt, Mr. Krabs declares they will have to work for him forever. We then cut to "One Eternity Later", and their skeletons are still working at the Krusty Krab.
- "I'm with Stupid", which revolves around Patrick pretending to act smart for his parents' visit on "Starfish Day", randomly reveals at the end that the "parents" who visited are just a random starfish couple named Janet and Marty, and Patrick's real parents have been pestering Squidward. And then Janet and Marty remember that they don't even have a son and leave. What.
- "Doing Time" ends with the events of the episode turning out to be All Just a Dream Mrs. Puff was having while SpongeBob was crashing the boatmobile they were both in...but then it turns out to be a dream within several dreams, with Mrs. Puff waking up in the same time and place with characters and elements from the episode appearing around her each time. The episode ends with Mrs. Puff still in the cycle of waking up in the crashing boatmobile and giving up with a resigned: "Oh, forget it...". It really makes you wonder how she was able to fall asleep while screaming.
- "Graveyard Shift" ended with all the strange occurrences being explained away as the actions of a nervous new potential employee of the Krusty Krab... except for the flickering lights. It turned out that it was the live action version of Nosferatu turning the light switch on and off all along, and nobody seems to be bothered by this.
- "I Had An Accident" ends with SpongeBob, Patrick, and Sandy being attacked by a gorilla (played by a live-action human in a cheap costume). When SpongeBob wonders out loud "What's a gorilla doing underwater in the first place?", the gorilla stops his rampage and tries to explain himself, then suddenly shouts "George, they're onto us!". Then a pantomime horse shows up and shouts "Let's get outta here!", and the gorilla rides off into the sunset on him. The weirdness of the ending is then lampshaded, as it zooms out to reveal a live-action family watching the episode on TV; they're completely puzzled by the whole thing and switch the TV off, ending the episode. Said lampshade-hanging only makes it even weirder.
- "Spy Buddies" ends with Mr. Krabs and Plankton revealing that they challenged each other to see who could do each other's jobs better. They use disguises to cover up who they were during the switchup. Krabs fitting in a Plankton costume is confusing enough, but then SpongeBob and Patrick begin to take costumes off themselves, revealing they are Sandy, Squidward, and each other. What.
- "Spongehenge" ends with SpongeBob returning from Jellyfish Fields, only to find Bikini Bottom destroyed by a windstorm. Cut three thousand years into the future, and alien tourists are visiting the Stonehenge-esque structure that SpongeBob built earlier in the episode out of stone statues of himself.◊Alien: To this day, no one knows why these mysterious statues were created or by whom. All we know is that the genius of their design has caused the annual migration of jellyfish to their wondrous tune.
- "Back to the Past" ends with multiple SpongeBobs and Patricks arriving from different timelines and universes.
- "No Pictures Please" begins with a parody of The Twilight Zone's opening as a sort of Framing Device. The actual episode is about Patrick showing a shutterbug tourist around Bikini Bottom. Nothing truly bizarre happens until the very end, when it's shown the tourist's camera never had any film in it. The tourist then admits he never took pictures or even had a camera in the first place, which causes the camera to disappear in a Puff of Logic. The tourist then says he was never there at all and vanishes as well. The other characters run away from fright, and then the screen turns black, filling with stars. The narrator closes the Framing Device by saying "Things always get weird in 'The Tidal Zone'", and then laughs. Finally the tourist suddenly appears on screen and takes one more picture. End episode.
- The premise of "Cuddle E. Hugs" (already one of the show's stranger episodes) is that SpongeBob (and later others) gains the ability to see the eponymous imaginary giant hamster after eating rotten Krabby Patties. After things take a turn for the worse with everyone being "eaten" (except not really) by Cuddle E., SpongeBob meets Cuddle E. again and manages to feed the protesting hallucination a rotten Krabby Patty himself. Smash Cut to Cuddle E. waking up as a normal, non-animated hamster in a hamster cage sitting in a child's bedroom covered in SpongeBob posters and memorabilia."Aw, pellets..."
- "FarmerBob" mostly consists of SpongeBob and Patrick getting into wacky hijinks while spending a day working on Old Man Jenkins' farm until the very end when all of a sudden hillbilly aliens invade the farm because they thought there was a party (thanks to Patrick inadvertently writing something in a field that read like a party invitation to them). The rest of the episode is everyone having a hoedown and the episode proper ends with the aliens randomly coming back after leaving to abduct SpongeBob, Patrick, and Mr. Krabs.
