"Shut Up!" is the second single taken from Simple Plan's second studio album, Still Not Getting Any.... It is more of an "in your face" track, as the band are telling music critics, who generally deride the band as commercialized drivel, to just 'shut up!'. It could also be seen as a track where the speaker is telling his girlfriend to "shut up". Simple Plan performed this song on the 2005 Kids' Choice Awards, as a way to promote the album.
The video starts out with the boys walking down the street, into the Millennium Biltmore Hotel in downtown Los Angeles. Once inside, they walk into the ballroom, where there is a fancy party going on. Grabbing their instruments, they start playing, creating a huge disturbance. The party goers begin to get very upset, as the members of Simple Plan begin jumping on tables and destroying everything. This is where Pierre Bouvier first does his knee dance. As some of the younger members of the party begin to start getting into it, a man leans towards Bouvier and says "Dude, there's been a major mix up." Bouvier asks "Are we in the wrong place?" and, upon confirmation, exclaims "I thought something was up!" The video then goes through a fast motion rewind, and ends up in a club, where the remainder of the song is played.
