"Mama Said Knock You Out" is the fourth single by rapper LL Cool J from his fourth studio album of the same name. 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 was produced by Marley Marl with help from DJ Bobcat along with LL. The single reached number 17 on the Billboard Hot 100, was certified Platinum by the RIAA, and won the Grammy Award for Best Rap Solo Performance. The song takes various shots at Kool Moe Dee.
