"Mama Said Knock You Out" was a hit single by LL Cool J off of his album of the same name. The song's famous beginning is "Don't call it a comeback / I've been here for years." Before "Mama Said Knock You Out" was released many people felt that LL Cool J's career was waning; his grandmother, who still believed in his talent, told him to "knock out" all the critics. The song was produced by Bobby "Bobcat" Ervin and DJ Marley Marl and won Best Rap Solo Performance at the Grammy Awards of 1992.
The music video features LL Cool J in a boxing ring, rapping into a microphone similar to the one an announcer would use in a boxing match. Frequently we see shots of him working out and scenes of a boxer being punched out.
Bob Dylan has this song on his playlist for Episode 2 of The Theme Time Radio Hour.
In Living Color parodied this song with Shawn Wayans as LL Cool JJ and the song was "Mama's gonna kick me out"

The lines "Don't you call this a regular jam, I'm gonna rock this land, I'm gonna take this itty bitty world by storm, And I'm just gettin warm" was sampled as a chorus for the track "I'm just gettin warm" by Busta Rhymes for his upcoming studio album "Back On My BS"
