Greg "Shock G" Jacobs (also known as Humpty Hump) was the leader and mainstay of the alternative hip hop group Digital Underground and was part of the group since its creation in 1987 in Oakland, California. Released in the spring of 1990, "The Humpty Dance", a humorous dance number that reached #11 on the Billboard Hot 100, #7 on the R&B charts, and #1 on the Billboard Rap Singles chart was the second single of their debut album Sex Packets. It was rapped by Shock G's alter ego Humpty Hump, and featured a drum track with over 50 confirmed usages in other songs.
