In this song, Eminem portrays a murderous sociopath as he raps about how he his evil evolved. It's done in character as Slim Shady, the dark and impulsive side of his personality.
Eminem goes for comic shock value on this track, which is in line with the theme of the album. "It's just a stupid f--king animated story about stereotypical white trash," he told Q magazine. "It's about being a trashy kid growing up with no morals and no f--king values. Every day is the same, the world keeps turnin', and I wanna get off this motherf--ker. There's not even a meaning in that song. Not all songs have to have meanings to 'em. It's just funny, y'know? Laugh."
