SpongeBob and Patrick are at Near Mint Comic Books, and Patrick sees an ad for a mail-in offer promising to adapt a poem into a song. Patrick has a flashback while he is trying to write his poem at SpongeBob's house. He remembers a time from when he was younger in which he recited the poem: "Roses are blue. Violets are red. I have to go to the bathroom." The gym teacher told him that he had told him repeatedly that it was gym class, so he had the class throw dodgeballs at him.
Nonetheless, he has a plan to write his song fast so it would be a masterpiece and he will not get hit by dodgeballs again. Patrick takes SpongeBob's comic book money to enter $100 and submits an entry called "I Wrote This." The song does not make much sense and it is so awful that even the paper smells terrible when he submits it, and the band dies recording it. When the two listen to the song through a large loudspeaker, it turns out to be so bad that it melts down SpongeBob's house. SpongeBob, however, enforces to Patrick that it is the greatest song ever, so he and Patrick try to get the song on the radio.
They are immediately kicked out by the radio station, so, finding a different method, they climb up the radio tower and use a piece of chewed gum to stick the record player to the top of the antenna. The song is heard throughout the town, which causes rioting, literal head explosions, and a plane crash into a fireworks storage building. The town hates the song so much that they form an angry mob, which is headed by Fred. They yell about how much they hate the song and run SpongeBob and Patrick down to the ground.
While it looks like they are getting beat up, it turns out that SpongeBob and Patrick are making random noises with musical instruments and a chainsaw. Patrick said that was his new song, which the mob admits that it is not that bad and it is better than the first one Patrick made. Patrick starts to sing the song in front of everyone until his old gym teacher arrives, saying that Patrick never learned his lesson, which leads to the two getting humiliated as the angry crowd pelts them with dodgeballs as punishment.
- Bikini Bottomites being annoyed by Patrick's song.
- SpongeBob's arms being removed from his body.
- Patrick failing to write good poems, causing his gym teacher to prompt everyone to pelt him with dodgeballs.
