After discovering he has rituals, Lincoln worries he's predictable and vows to change it up.
While waiting for the bathroom, Lincoln is informed by Lisa that the bathroom is all his, commenting how he always goes the bathroom at precisely 7:03 AM. Later on, Lynn Sr. asks the kids what they would like for breakfast this morning, but Lynn Sr. has already made Lincoln's order in advance, where he points out that he always wants a breakfast burrito with extra cheese and no taters in it. Then while combing his hair, Lincoln is told by his sisters to hurry up before they're late for school, and when he jumps into the van, Lucy and Lola tell Lincoln that he's always the last one to leave the house, and comment why he takes so long, despite wearing the same orange polo every day. At school, Mrs. Johnson announces that they're going to study astronomy, and Mrs. Johnson comments that she knows that Lincoln will pick Clyde as his partner, with Zach commenting that Lincoln always chooses Clyde to be his partner. During gym class, Coach Pacowski informs his students that today, they're going to be climbing rope, and Lincoln not wanting to do that, tries to excuse himself, but Coach Pacowski already excuses him, stating how Lincoln always excuses himself to avoid climbing rope.
That night, Lincoln has a nightmare where he can't stop thinking about what everyone has told him (even his teeth fall out and tell him that he's boring because of how predictable he is). This causes Lincoln to wake up in panic, and declares that he is predictable, and decides that he needs a new strategy to change things up a bit.
The next day, Lincoln wakes up an hour early to use the bathroom, tells his father that he would like biscuits and gravy with hot sauce instead, digs through a box of hand-me-down clothes for a new look, and enters the van earlier than everyone else. These sudden changes impress his family, saying that they weren't expecting Lincoln to be so different. At school, Mrs. Johnson announces that they're going to be practicing calligraphy, and Lincoln suddenly states that he wants Stella to be his partner instead of Clyde. This causes Clyde to hyperventilate, since he's aghast to the idea of Lincoln being different. During gym class, Lincoln surprises Coach Pacowski by saying that he volunteers to climb the rope first, and successfully does so, but at the same time, Clyde, fearing Lincoln's new personality, calls up Dr. Lopez, saying that he might have a panic attack.
The next day, Lincoln attempts to copy what he did yesterday, but thinking that the results will be predictable, decides to go with a new look, impressing everyone again. Before long, Lincoln begins wearing a new outfit, and doing a different routine every day, much to everyone's surprise, but to Clyde's distress. Soon enough, Lincoln runs out of hand-me-down clothes to wear, and when he takes a nap in the box, he has another nightmare, this time, his family and classmates tell him that no matter how hard he tries to be unpredictable, they've already seen him do it before. This causes Lincoln to wake up in a panic yet again, and ponder his situation.
When Lincoln and the younger sisters are dropped off at the elementary school, Lincoln announces to them that he was being so unpredictable the past few days because he feared that he was so predictable, nobody wanted to hang out with him anymore. The sisters and classmates, confused at what Lincoln means, tell him that he's not boring, stating that they too have their own daily habits, which relieves Lincoln, now knowing that he's not alone. Suddenly, Clyde runs up to Lincoln and hugs him, wishing him to never change.
