"Cool Jerk" is a popular song written by Donald Storball and originally performed by The Capitols. Released in 1966, it reached No. 2 on the American R&B chart, No. 7 on the pop chart and No. 9 on the Canadian Singles Chart. The backing track for this song was actually recorded (secretly) by the Motown house band The Funk Brothers.
Per one of the Funk Brothers, the song was originally to be called "Pimp Jerk." This was taken from watching neighborhood pimps, who would dance in the clubs, but were too "cool" to do the jerk like regular folks. Their version was subsequently named "the Pimp Jerk." The producer was afraid that a song with the word pimp in the title would be banned or not receive much positive attention, and had the title changed to its current form.
