Directed by Frank Borin, the video focuses on the band members going to their high school reunion, while another version of them performs the song onstage. They arrive, instantly recognizing people from the past that bullied them. During a montage, the band gets revenge on their former bullies in situations similar to their high school past. The first flashback shows Gary Wiseman getting a wedgie by some bullies, who hang him on the flagpole by his underwear. Gary takes his revenge by grabbing the underwear of the bully and pulling it over his head while he is still wearing it. The next flashback involves Erik Chandler getting a note reading "kick me" taped to his back by a jock. Erik gets him back by sticking the punch bowlsign on his back; this starts a queue of people ready to punch the jock, including a nun, a pimp, a cowboy and a knight in armor. After the sequence of celebrities references, Jaret Reddick invites a guy onstage who had embarrassed him at high school, by pulling down his pants in front of a girl he was obviously keen of, revealing his pink underwear. Jaret pulls his pants down onstage as his act of revenge. The popular guy then explodes in embarrassment after a sign stating "TOO SMALL FOR TV" appears strategically over his crotch. Finally, Chris Burney has a flashback of him being slipped a laxative by a cheerleader and manages to get his own back by consuming a massive sub sandwich, a chili removed from his pants, a white mouse, gasoline, and a goldfish. After jiggling around, he then confronts the popular girl and presents the contents of his stomach upon her–by projectile vomiting. After Chris' revenge, the band finishes the song, Jaret sticks his guitar pick to his rather sweaty forehead and the video ends with a disclaimer that states "No animals or children under 15 were harmed in the making of this video".
A separate edit of the song was recorded for Radio Disney, which altered the lyrics throughout:
In the first verse, the line ".. all the total dicks" is changed to ".. all the popular cliques".
In the chorus, ".. who's having sex" is changed to ".. what's been suppressed", and ".. who gets the honeys" is changed to ".. who thinks they're funny". Also, the alternative version of the second chorus has the line "Who’s in the club and who’s on the drugs, Who’s throwing up before they digest" removed entirely.
The second verse line "How did Mary-Kate lose all that weight? And Katie had a baby so I guess Tom's straight" is changed to "How does Mary-Kate always look so great? And Katie's with Tom, OK, I've got that straight".
