It is a comedy/novelty song which parodies the style of the Beastie Boys, as well as the main guitar riff being based on the melody of the Jewish folk song "Hava Nagila" (guitarists Scott Ian and Dan Spitz—as well as all the members of the Beastie Boys—are Jewish). On live performances, Joey Belladonna and Charlie Benante would switch places, Benante performing some of the raps and Belladonna drumming. A 7" single also appeared, containing only tracks 2 and 3. As of 2006, I'm the Man had sold over 178,000 copies in the U.S since the beginning of the SoundScan era.
The beginning of "I'm the Man" features an electric guitar sample of Jewish folk song "Hava Nagila", which can also be heard in the chorus. The chorus' lyrics are borrowed from one of Taylor Negron's lines in the Rodney Dangerfield movie "Easy Money." Rather than using a sample, the lines are performed by Frankie Bello. Anthrax even used one of Sam Kinison's famous primal screams for the song.
