Mama Said Knock You Out (song)

"Mama Said Knock You Out" is a song by American rapper and actor LL Cool J, released in February 1991 by Def Jam and Columbia as the fourth single from his fourth studio album of the same name (1990). The song famously begins with the line, "Don't call it a comeback/I 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 his critics. The song takes various shots at Kool Moe Dee. It was produced by Marley Marl with help from DJ Bobcat along with LL.

"Mama Said Knock You Out" reached the top twenty on the US Billboard Hot 100, peaking at number 17. The single was certified Platinum by the Recording Industry Association of America (RIAA) and won the Grammy Award for Best Rap Solo Performance. In October 2023, Billboard ranked "Mama Said Knock You Out" among the "500 Best Pop Songs of All Time".

Background
The song uses samples from James Brown's "Funky Drummer", the Chicago Gangsters' "Gangster Boogie", Sly & The Family Stone's "Trip to Your Heart", the drum break from Sly & the Family Stone's Sing a Simple Song, and LL Cool J's own "Rock the Bells" (from his debut album Radio). The music video features LL Cool J in a boxing ring, rapping into the announcer's microphone. Intercut with this are clips of boxing matches and LL Cool J exercising.

LL Cool J said in his autobiography that the idea for the song came from a discussion with his grandmother. He had said to his grandmother that he felt that he couldn't survive as a rapper now that gangsta rap was popular and he was being dissed by several up-and-coming rappers. LL's grandmother responded, "Oh baby, just knock them out!" She is featured in the closing scene of the music video, saying "Todd! Todd! Get upstairs and take out that garbage."

Critical reception
Jon Wilde from Melody Maker said in his review of the single, "It is rather gratifying to see this arrogant, obnoxious young feller struggling hopelessly to resurrect his career. The Roy Kinnear of the rap scene returns with more of the same bilious rubbish. Nice hat though." Another Melody Maker editor, Robin Bresnark, remarked, "Possibly the first mainstream rap track which, for me, had the vicious beats to fully match its rhetoric." David Quantick from NME wrote, "'Mama Said Knock You Out' demands that we don't call it a comeback. I don't think we need go as far as that." NME editor Paolo Hewitt felt the track is "a vicious and exhilarating display of the man's talents." David Fricke from Rolling Stone remarked that the rapper "obliges big time with producer Marley Marl's steely, stripped-back beats and his own verbal fisticuffs" on "the super-slammin'" track.

Legacy
Rolling Stone ranked the song 29th in a 2012 list of the "50 Greatest Hip Hop Songs of All Time". In October 2023, Billboard magazine ranked "Mama Said Knock You Out" number 406 in their list of the "500 Best Pop Songs of All Time".

Bob Dylan played it in the final slot of the "Mothers" episode of Season 1 of Theme Time Radio Hour in 2006. Dylan noted the song was "in the same tradition as the Dozens" and recited the first verse before playing it.

LL Cool J re-recorded a new version along with the Roots by mashing up with Here I Come to promote the NBA in-season tournament.
