Crazy Bus

"Crazy Bus" (also known as The Crazy Bus Song) is D.W.'s most favorite song that was written by Arthur writer Joe Fallon. However, her brother Arthur dislikes the song just as much as he dislikes her favorite show, Mary Moo Cow, and he claims that "Crazy Bus" is the worst song ever written, due to the fact that D.W. plays it constantly at his expense. However, D.W. disagrees with Arthur, and says that it is the greatest song ever written. The song was first heard in Buster Baxter, Cat Saver, and has been recycled in some subsequent segments.

In Play it Again, D.W., it is shown that Crazy Bus has a fairly large following, as many of Arthur's friends (Notably Buster) started listening to the song, and also hosted a live concert event. However, no matter how many times it is played, Arthur absolutely detests the song, and on other occasions his friends have said it is terrible.

In the aforementioned episode, D.W. loses her Crazy Bus CD and immediately accuses Arthur of stealing it. However, it was later found that her parents accidentally took it during a mixup with the music they had hoped to play at a high school reunion. Arthur was also horrified to learn that Grandma Thora had given D.W. a tape of Crazy Bus: The Motion Picture.

In Revenge of the Chip, D.W. again claimed that Arthur had stolen the CD when complaining about how everyone was humiliating her over the green chip incident, only to be reminded by Arthur than Mom and Dad had made that mistake. Fortunately, D.W. doesn't accuse Arthur of this crime nearly as much as she does with the infamous snowball incident.

In My Music Rules, D.W. takes her obsession with the song further when she suggests to Ms. Turner that they get "the guy who wrote Crazy Bus" to play music for the children at the library. They instead get real-life musicians Yo-Yo Ma and Joshua Redman to come and play, and they surprise everyone with their own rendition of Crazy Bus using a combination of classical and jazz music. This version sounded much better than the one D.W. usually plays, and even Arthur finds it more good.

D.W. is the biggest fan of Crazy Bus, and in the course of one week played it at least 532 times, according to Arthur. Unfortunately for Arthur, few have acknowledged D.W.'s obsession with the song, even though she plays it nonstop regardless of who it disrupts or where she is present.

She later calls the song a baby song and dismisses the song entirely. This is a reference to Joe Fallon leaving the show. Fallon was the writer and the performer of the song.
