Rolling Stone reported that the skit was a spin-off of Fallon's "History of Rap" series, which features Fallon and Justin Timberlake.
This isn't Smith's first musical collaboration with Fallon. In 2015, the two performed Rob Base and DJ E-Z Rock's "It Takes Two" with an iPad app. They danced together in "The Evolution of Hip-Hop Dancing," which included the Carlton dance. In 2012, the pair did a 1920s radio skit.
