The Best Day Ever

Summary
It's a beautiful afternoon and everyone is reminiscing about their best days. Everyone, that is, except Arthur. Is it possible he doesn't have one?

Plot
The episode begins with Arthur watching a clip from The Lousy Week, then he decides to show the viewers his Top 5 Worst Days Ever, which include, for #5, the day he was fired from his piano teacher (Arthur Plays the Blues), for #4, ripping his pants in school for EVERYONE to see (Arthur's Underwear), for #3, saying goodbye to his best-friend, Buster, for his trip around the world (Arthur's Faraway Friend), for a whole year, 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.

TITLE CARD

Its a beautiful afternoon in Elwood City, and at the park, Arthur, Binky, Buster, George, and 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 other 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 he joined the "Tough Customers" in The Boy with His Head in the Clouds, but he says that was his 2nd best day) was the time that his family adopted 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 was the first time time he felt like a big brother.

When Arthur's next, he claims he is still thinking of one, and George is next instead. His best days started as one of the worst days ever, when at the poetry reading, organized by Fern, the unthinkable happened to him, as Wally began to fall apart! While trying to fix him, Wally said to go on without him, but George didn't have the courage, until Arthur talks to George and said that it'll be okay, and when he reads his poem, as so it turns out, it turns out okay!

When he takes Wally out to tell jokes, Arthur thinks about what was his best day, when Sue Ellen interrupts him to say what was his best day, but he fakes an itchy throat, making Sue Ellen go next. Sue Ellen's best day ever was when Arthur found Sue Ellen's diary. He claims he didn't open it, which Sue Ellen believes. Yet Binky thinks Arthur took a little peek inside. From then on, Sue Ellen knew that she had trustworthy friends.

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, then 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've happened, so even though he doesn't have a best day, he till has a piece of theirs! Finally, Arthur finds his best day: Today, with his friends, stating that its "perfect". Then, a thunderstorm arrives and it begins to rain. Even though Buster said that it might've ruined his best day, its still great. Arthur catches up with the others, asks if they want to come to his house, and the episode ends.
