Chris Rock is working hard these days promoting his newest film, Top 5. The next stop on Rock's press run, was a sit-down with Jimmy Fallon on The Tonight Show. A big moment in the film consisted of Rock detailing his top five favorite rappers of all-time. In the film, his character Andre Allen named Scarface, Notorious B.I.G., Jay Z, Nas, and Rakim, with LL Cool J serving as his sixth man. This past Monday (Dec. 8), Rock entered Fallon's domain and challenged the late night host to name his top five rappers.

Fallon's top five list included the likes of Jay Z, Eminem, the Beastie Boys, Run D.M.C., and "Rappin Duke," which was a 1983 parody track made by Shawn Brown impersonating John Wayne. In addition, during the interview Rock revealed how he was once signed to Atlantic Records as a rapper and DJ.

Check out the clip. Top Five will be in theaters Dec. 12.
