"What We're All About" is a reworked version of "Dave's Possessed Hair/ What We're all About" from the band's first EP, Half Hour of Power.

Part of the first verse is rapped in an acappella version in the beginning of the "Fat Lip" music video.

[citation needed] In September 2001, Whibley mentioned that the band wanted to feature rappers Redman and Method Man in the reworked version of the song,[3] but this did not end up happening.

It features the Sum 41 band members playing upside-down with their instruments chained to the roof as they perform on the rooftop to the audience below.

Near the end of the video, the band members leap into the audience below as the party segues into the scene from the movie where Spider-Man returns from his battle with Green Goblin with a cut on his arm.
