The French Narrator introduces another SpongeBob SquarePants special, hosted from Encino, California as it was 100 million years ago. From his cave-house, Patchy the Pirate, in a caveman costume, is introducing prehistoric times and talking about how great they were. However, Potty, in a futuristic robot costume, appears and says that prehistoric times were "lame" and the future is "where it's at." They begin arguing over whether SpongeBob himself likes prehistory or the future better, and while working at the Krusty Krab, SpongeBob feels a disturbance and tells Mr. Krabs that "I've got the strangest feeling that somewhere a pirate and parrot are arguing about me. And, the parrot is winning." As Patchy and Potty continue to argue, Patchy begins the SpongeBob episode.
The cartoon features prehistoric versions of SpongeBob, Squidward, and Patrick, named "SpongeGar," "Squog," and "Patar," respectively. SpongeGar, who is sleeping in his pineapple-shaped cave, is awakened by a distant herd of monstrous purple creatures, who produce a sound identical to that of SpongeBob's alarm clock that knocks the rock on SpongeGar. SpongeGar takes his version of Gary, who is bigger than the prehistoric pineapple itself, out for a walk, and he leaves a slime trail all over Squog's front yard. Squog comes out with one of his two clubs to complain to SpongeGar, but slips on the slime trail, sliding into Patar's rock, awakening its occupant, and eventually crashing back into his own house. SpongeGar and Patar begin to play, and SpongeGar uses a hollow log to blow a bubble. It then starts raining, and eventually lightning strikes the log, setting it on fire. The three experiment with it, and soon realize that it can be used to cook food, and begin cooking various items with it, including flowers, the top of a mushroom, a kelp reed, a wood stick (Patar eats it), a prehistoric ancestor of Eugene H. Krabs, seaweed flowers that look similar to corn on the cob, a green plant that looks like spaghetti, rocks that take the form of popcorn, and a Krabby Patty made of sand.
Over the commercial break, Patchy and Potty continue to fight, now keeping score between the future and the past. Patchy brings in a real live caveman, but Potty brings in a futuristic robot who begins repeatedly shooting the caveman with lasers.
At the end of the day, SpongeGar, Patar, and Squog are full from eating and say goodbye to each other as they head over to their homes. Suddenly, SpongeGar, Patar and Squog stop walking and they turn around, realizing that the fire is still out there. The three of them start fighting over whom will keep the fire. They continue fighting until it starts raining again and puts the fire out. SpongeGar and Patar apologize to each other for fighting, but Squog blames them for putting it out and attempts to hit them over the head. Before he can do so, however, lightning strikes him and SpongeGar and Patar cook marshmallows over his charred body.
After the episode ends, Patchy is shown sitting outside his cave, apparently having lost to Potty. However, Potty comes outside and invites him back in, where Cavey the Caveman and the Robot Android Cyborg DX-294888 do a rap called "When Worlds Collide." The song montage features scenes from SpongeBob B.C. and "SB-129." The episode ends with Potty giving Patchy a "gift:" a Tyrannosaurus Rex, which begins chasing him as Patchy says bye to the viewers.
SpongeGar, Patar, and Squog speak in a primitive language similar to English. Many words and sounds are taken from or based on English words/sounds.
it belongs to you, not me!
Wait a minute
wait a minute
why you little!
Edited Out For DVD
Despite the The Complete Third Season DVD having no commercials, the second half cuts in after the French Narrator speaks in the still shot of animation. Because of this, Patchy getting hit by a rock is removed. But, this scene can still be found on the "SpongeBob Goes Prehistoric" DVD and VHS. It can also be found on the "Nick Picks Vol. 1" DVD.
The music used in the introduction of SpongeGar, Patar, and Squog is exactly the same music used in the title card of "Rock Bottom."
Running Gag: Patar putting salt on items and then eating them.
Excluding the narrator, Patchy, Potty, Cavey, Potty's Robot, the actual SpongeBob and Mr. Krabs during the "Meanwhile" time card, none of the dialogue in the SpongeBob episode was edited in the Korean version.
Most of the dialogue during the SpongeBob segment was left untranslated in the Russian dub, except for the narrator and a few parts, where the characters speak proper Russian instead of cavemen.
This is the second time an interjection is used as an episode title. The first time this was done is in "Arrgh!"
This episode has the shortest title. It is tied with "F.U.N.", as both episodes only have three letters in their name.
Patchy's Caveman Cave house is in the Cretaceous period, while the past part of the cartoon part of the episode is in the Jurassic period.
The Prehistoric part takes place sometime between 150,800,000 years and 148,500,000 years ago because Ammonites existed 400,000,000-66,000,000 years ago, Sponges started to exist sometime between 635,000,000 years and 541,000,000 years ago, Starfish started to exist sometime between 541,000,000 years and 485,400,000 years ago, Pterodactyls existed 150,800,000–148,500,000 years ago, crabs started to exist sometime between 201,300,000 and 145,000,000 years ago, Octopi started to exist 323,200,000, Snails started to exist sometime between 497,000,000 years and 485,400,000 years ago, and Jellyfish (shown on SpongeGar's cave wall) started to exist 505,000,000 years ago.
This episode aired in Germany on September 18, 2003, before it aired in the USA.
The atonal singing of the barbershop quartet is a reference to the piece "Requiem for Soprano, Mezzo Soprano, Two Mixed Choirs, and Orchestra" by György Ligeti, which was used in the film 2001: A Space Odyssey whenever the monolith appeared.
Patchy finding Cavey in a block of ice and naming him "Cavey" is the same origin of how the Teen Angels found Captain Caveman.
The scene in which SpongeGar realizes that he can use a stick as a tool to take a piece of coral out of the fire pays direct homage to the Dawn of Man sequence from the film 2001: A Space Odyssey, a famous scene in which a group of apes learns to use a bone as both a tool and weapon. In both cases, the narrative has portrayed these stories without the use of conventional dialogue (using nonsensical cave-ish speech in Ugh and using ape noises in 2001.
The music is also a direct homage, with a modernistic wailing piece composed by György Ligeti used while SpongeGar makes his discovery, and the classical piece "Also Sprach Zarathustra" by Richard Strauss played after SpongeGar's discovery, mirroring the use of those same two pieces of music in 2001.
B.C. being "Before Comedy" is a parody of what it actually is, "Before Christ."
The opening image of Prehistoric Bikini Bottom looks similar to the swamps of Degobah in Star Wars.
The scene where SpongeGar and Patar clap on and off the storm is a reference to The Clapper light switch system.
The scene where Squog crashes into a tree on a vine, it's a reference to when George of the Jungle crashes into a tree, as in, "Watch out for that tree".
When Patar punctured his lip, the stick is thick, but when SpongeGar stomps on a little crab take out the stick out of Patar's lip and impaled a little crab and give him to it; the stick is thin.
When Gary gets a snail trail on Squog's rocks, it is on the one closest to his house, but when Squog looks out the window, it is on the third one from his house.
In the original airing, the captions spell Patar's name as Pathar.
YTV's captions spell Squog's name as Squd.
Patchy has brown eyes throughout the episode, but when his eyes bulge out of his head, they are blue in color.
Squog doesn't have a door on his house until he takes the fire to it.
When Patchy tries to create fire, his hook is shown on his left hand, while in other scenes, it is on his right hand.
Also, in the next frame after he introduces himself, he does not have his hook.
While SpongeBob was sniffing his first charred flower on a stick, the roots were seen over his beard where the root parts over his beard were colored red.
When Squog, Patar, and SpongeGar went to their homes, they were still fat. But when they forgot the fire, they turned skinny fast.
When Squog was choosing which club to use, he put the one he didn't want on the right. When it showed a close-up view, it was moved to the left.
