Editing The Best Day Ever

The episode begins with [[Arthur Read|Arthur]] watching a clip from "[[The Lousy Week]]", then he shows the viewers his Top five Worst Days Ever, which include, for #5, the day he was fired by his piano teacher for not practicing ("[[Arthur Plays the Blues]]"), for #4, ripping his pants in school for EVERYONE to see ("[[Arthur's Underwear (episode)|Arthur's Underwear]]"), for #3, saying goodbye to his best friend, [[Buster Baxter|Buster]], for his trip around the world ("[[Arthur's Faraway Friend]]"), for #2, the time D.W. accused him of stealing her snowball, and was all over him for a few days, and before he could show his #1 worst day ever, D.W. interrupts him by playing a video of Arthur as a baby, making her tease him about him being a baby. Arthur then says that he has found a brand-new worst day, before pressing a button on his remote control, and making D.W. disappear virtually.

Its a beautiful afternoon in Elwood City, and at the park, Arthur, [[Binky Barnes|Binky]], [[Buster Baxter|Buster]], [[George Lundgren|George]], and [[Sue Ellen Armstrong|Sue Ellen]] are laying down on the grass, relaxing and soaking in the sun, and Arthur thinks that this is one of the best days ever, with the others agreeing, yet Buster says that it might not make his Top 10 list, which makes Arthur question. Binky then says that he doesn't have a list, but his best day ever (George guessed it was when Binky joined the "Tough Customers" — which was instead his second best day) was the time that his family adopted [[Mei Lin Barnes|Mei Lin]], his little Chinese sister ("[[Big Brother Binky]]"). He remembers that he cured Mei Lin's crying by showing her his "Monkey-face", which stopped her from crying. He said he could've had his own show! But when she met Arthur, it wouldn't work anymore. Then when Arthur's family met Binky's family at a Chinese restaurant, Binky thought that Mei Lin would rather have Arthur, but he realized that Mei Lin was being taught by Binky, and that was the first time time he felt like a big brother.

When Binky says to Arthur to go next, Buster pipes up and says his best day ever, when Buster couldn't get to sleep, but was counting puffins, when a light appears into his room, coming from a U-F-O in the shape of a donut; strawberry shaped people come out and proclaim Buster as their new king to rule "Fruitopia" forever, before realizing DREAMS don't count from Arthur. Buster then says his best day ever was when he came home from around the world to play checkers with Arthur ("[[Buster's Back]]"), making Buster say he missed Arthur, yet he still won the game!

When Arthur's turn has finally come, he says he doesn't have one. He states that he had really good days, but not one that tops the whole lot. Buster and Sue Ellen tell Arthur that having a best day isn't important, but he might have one someday, and Arthur turns down an offer from Binky if he wants to join the Tough Customers. George then realizes that Arthur was in all of their best days, and without him, none of them would have happened, so even though he doesn't have a best day, he still has a piece of theirs! Finally, Arthur finds his best day: Today, with his friends. He states that it’s "perfect."

 

Then, a thunderstorm arrives and it begins to rain. Even though Buster mentioned that it might have ruined his best day, it's still great. Arthur catches up with the others, asks if they want to come to his house, and the episode finishes.
