The Diary of a Wimpy Kid, The Third Wheel, is about Greg being a third wheel with a popular girl and his best friend. Greg's middle school wants the students to be involved with the student body government, giving and handling school ideas based on dances and other social committees. Rowley (Greg's best friend) becomes chairman, who is the person who gives ideas for social events to the student body government. Rowley suggested the idea of having a dance and the girls in the student body designed the theme and the decorations for the dance. Rowley then told Greg about the dance and Greg started to look for a dance partner. Although Greg did not have any luck finding a dance partner the first week, he was more successful the second week. Greg believed that because of was one of the few boys who acted mature, he would be the first one to have a dance partner. Most of the other boys would "pants" each other, act like animals, and do gross things. Since the girls wanted good-looking partners, Greg had little chance because most of the boys at his school were better looking than him. Greg was not ugly nor attractive, but he is mature. Finally, a day before the dance, he found a dance partner named Abigail. Greg told Rowley the good news. Unfortunately, Rowley did not have a partner, so he became the third wheel.
