Outside on the playground, and are teeter-tottering when runs over to them in a panic telling them it is March 15. Chester dons military garb and announces this on a loudspeaker, causing all the kids in the school to scatter. and blast off with rocket packs while hides in a tree. Timmy jumps into the bush near the tree while and appear nearby disguised as squirrels. They ponder what March 15 means; Cosmo believes it's "Be kind to squirrels day", but Timmy tells him that "every kid knows that March 15 is when is at his meanest". Cosmo and Wanda duck behind the tree when A.J. appears with a , in which he inserts a piece of Mr. Crocker's hair. Timmy grabs the tracking device and sees from a radar detector that Mr. Crocker is approaching fast.

At that moment, a with the license plate "FAIRIES" comes to a screeching halt in the school parking lot. Out steps Mr. Crocker dropping a number of weapons and traps (and a jack in the box) at his feet. A.J. screams for everyone to run for the safety of the U.S. education system and all the kids run toward the school. Wanda stays behind with Cosmo, who refuses to move until he gets his nuts. Cosmo is stepped on and flattened by Mr. Crocker as he marches toward the school. Inside Mr. Crocker's class, all of the students are in fear. Mr. Crocker screams for the students to put their heads down and places a magnet under Chester's desk; the magnetic attraction to his braces causes Chester's teeth to go through the desk. Crocker then turns to A.J. and asks him "If a tree falls in the forest but no one is around to hear it, does it make a sound?" causing A.J. to break down because he cannot give an answer. Crocker turns to Timmy, and because Timmy is not smart enough for a rhetorical question, and his teeth are not bad enough for a magnet, Crocker puts a dunce cap on Timmy and makes him sit on a stool surrounded by rabid dogs.

Timmy asks Crocker why he is doing this to them, to which Crocker responds with questions of his own: Why is he still a miserable school teacher, and why doesn't his tracking device ever find him fairy godparents? A.J. starts to explain that Crocker's "tracking device" has an egg beater and not a DNA sampler, but before he could explain the rest, Crocker silences him with another rhetorical question, ("What is the sound of one hand clapping?") causing half of A.J.'s head to flatten. Crocker hollers the final question—why the things he wishes for do not become reality—in Timmy's face, before leaving the class room and slamming the door. Timmy looks at the rabid dogs surrounding him, and his miserable friends, and discusses with his squirrel-disguised fairies nearby on the windowsill on why Crocker is so mean. Timmy wants to find out, but needs a way to get rid of the dogs first, so he entices them to chase Cosmo and Wanda. Timmy struts out of Crocker's class room, and makes his way to . Cosmo and Wanda poof themselves up as trash cans and Timmy hides behind them as Crocker screeches up into the drive way in his van. While Crocker stumbles out of his van and into his house, Timmy decides to get a better look with Cosmo and Wanda by turning them all into hummingbirds.

Mr. Crocker mutters about his stupid two-bit room, van and life. comes into his room saying that she baked his favorite stupid two bit dessert, a cake with "Happy March 15" written in icing on it. Crocker roars in anger, and his mother tells him she was just trying to cheer him up and that he should go back to being the happy boy he used to be. Mr. Crocker tells her that he cannot even remember a time in his life that he was happy, and slaps the cake away from his mother, causing it to splatter in his face. Timmy watches this from outside the window in hummingbird form, while Cosmo wonders why he does so much more sucking than humming as a hummingbird. Timmy notices that Crocker's mother said there was a time in his life when he was happy, but Crocker cannot remember it. Inside the house, Crocker wipes the cake off his face, but slips on more of it on the floor. Timmy decides to go back in time to learn more about what happened to Mr. Crocker that made him so mean. Cosmo asks him why he would help his worst enemy, to which Timmy replies that if he changed things for the better, he would stop tormenting him and the other kids. Timmy wishes up the , and also takes A.J.'s with him so he can easily find Crocker in any time period. Timmy hops onto the time scooter, and sets the time scooter to travel backward ten years.
