"I Ain't No Joke" is a song by rap duo Eric B. & Rakim, released as the second single from their debut studio album Paid in Full. It peaked at number thirty-eight on the Hot R&B/Hip-Hop Singles & Tracks. Described as one of the album's "monumental singles", Michael Di Bella wrote in the All Music Guide to Rock that "Rakim grabs the listener by the throat and illustrates his mastery of the rhyming craft". A music video was made for it, featuring dancing from Flava Flav of the group Public Enemy. The song was selected by Jay-Z for the NBA 2K13 soundtrack.
