Lincoln attempts to claim the best seat in the family van for a long road trip.
It's the night before the family road trip in the family van, also known as "Vanzilla". Lincoln explains that he's preparing to stake the night out on the "Sweet Spot", the only good seat in the car, as it protects him from the various inconveniences of the van, and the annoyances of his sisters. After he sneaks out and gets comfortable on the seat, he talks to Clyde over his walkie-talkie, and he asks who will be sitting next to him. After some thinking, Lincoln decides that Leni can sit next to him, since she is usually dazed out for the entire trip.
After convincing Leni to sit next to him, Lincoln goes back into the van, only for Clyde to point out the oversight of who will sit behind him. Following some more thinking, Lincoln convinces Lisa to sit behind him, but
only if she doesn't have to sit next to Luna. After speaking to Luna, she agrees to sit up front, so long as she isn't next to Lori. This leads to a chain of deals and agreements between Lincoln and his other sisters, as to who gets to sit next to who.
After finally finalizing the secret van seating chart under his mattress, Lincoln goes back to the Sweet Spot to get some sleep, and ignores Clyde's next question. However, by this time, the girls have gotten suspicious of Lincoln's intent, and after discovering his seating chart, they confront him about it. Lisa calculates that Lincoln has deduced which seat is the best seat in the van, and has angled his sisters in the positions most favorable to him, much to Lincoln's outrage. Now that they all know about the Sweet Spot, they demand that they get to sit in it. A melee ensues between them in the car, waking up the entire neighborhood in the process, including Rita, who tells her kids to get back to bed, and not to go in the van until 7:00 AM.
The Loud kids go back to their rooms, waiting impatiently for the clock to strike 7:00. When the time comes, Lincoln and his sisters begin a mad dash to the van, and have an even more violent and destructive brawl. By the time their parents call it to a halt, the van has been completely destroyed. As Lynn Sr. laments the loss of the van, Rita tells the kids to go back inside and that the trip is cancelled. She tells them that they're spending the weekend together on the couch until they learn to get along, much to everyone's chagrin.
With Lincoln's Sweet Spot plan ending in a total bust, he states that in a big family like his, you can't control every little thing. That said, he knows of another "Sweet Spot" on the couch. He then races out of his bedroom to the living room for it (and probably his sisters as well).
The Beatles - In Lincoln's flashback of his painful experience of Lynn playing Auto Attack with him, an ad on the back of the comic Lincoln is reading depicts a submarine colored yellow. This could be a reference to the Beatles' iconic 1966 song Yellow Submarine.
Several times in the flashbacks, Lincoln is shown reading comic books with his clothes on, but in a later episode, "Undie Pressure", reveals he reads comic books in his underwear, because he claims reading them with clothes on is uncomfortable for him.
The sweet spot is shown to be the first seat on the left, in the middle row. However, the flashback of Lincoln in the "slanty" seat is shown to be where the sweet spot is, since the back row was crossed off, and the first seat from the left in the front had the speaker.
When Lincoln is packing his things into his bag, it includes the robot action figure he keeps on his dresser, but in the next shot, it's back on his dresser.
In Lincoln's flashback of the "spring" seat, it's shown to be the second seat from the left, but in the flashback with Lola, he's sitting all the way to the left.
When Lincoln says "That it turns into the wild, wild west." both his arms are dislocated.
When Lola says "Beauty before age.", her eyelashes are missing.
When Lana shoots a pea into Lincoln's mouth, he falls out of his seat, despite being restrained by his seat belt.
Luna said she didn't want to sit near Lori, but Lincoln puts Luna and Lori in the front together.
Oddly, the only ones who were beaten up badly after destroying Vanzilla were Lincoln, Luan, and Leni.
When Lana says "Get him!", part of Luan's braces is missing.
Lucy is not seen racing with the others when 7:00 hits, but when the van is destroyed, she mysteriously appears.
Although, the top of her head is seen when Lynn is pulling Lincoln's head with her teeth.
When Rita (in silhouette) is yelling at the kids about Vanzilla, it is believed her's and Lynn Sr.'s room is upstairs, but the room they are in after Vanzilla is destroyed is Leni's and Lori's room, as their room is next to the living room.
At the end of the episode when Lincoln mentions a "sweet spot" in the living room, he says that it's close to the bathroom, despite the bathroom being upstairs and the living room is downstairs.
