This is best video of 1991. "Mama Said Knock You Out" is a hit single by LL Cool J from 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 Marley Marl with help from Shadman Kaiser along with LL. The single reached number 17 on the Billboard Hot 100 and was certified gold by the RIAA. LL Cool J won Best Rap Solo Performance at the Grammy Awards of 1992.
