The first music video version for the song features a montage of concert footage and the band's ordinary life in New Jersey. It was produced by Rafaela Monfradini and Greg Kaplan, who was also the director. It also features pictures of brothers, bassist Mikey Way and lead singer Gerard Way, when they were little kids and teenagers.
The second version music video depicts life inside a fictional American high school in the form of a mock movie trailer. The band appears as a group of outcast students who are repeatedly harassed by another group who are portrayed as popular kids. The band members then attempt to take on the popular kids and ultimately have a showdown in a hallway, with the band members armed with croquet mallets and the popular kids with lacrosse and hockey gear. It also has some clips expressing some emotions and clips of the band playing in a garage. The music video was directed by Marc Webb, and parts of it were filmed at Alexander Hamilton High School and Loyola High School in Los Angeles during August 2004. Greg Kaplan and Rafaelia Monfradini produced the video.
