Context paragraphs:
Hammertime: Hammertime is a reality TV show on the A&E Network about M.C. Hammer and his family, produced by 3Ball Productions Inc.  The title comes from the lyrics of Hammer's song "U Can't Touch This" (which became a popular culture catchphrase used in many television shows and movies), as well as his nickname.  Unlike previous shows Hammer was involved with, "Hammertime" focused only on him and his family who are living in Tracy, California in a large ranch-style abode situated on a two-acre corner lot.  At the time the show began, Hammer and his wife Stephanie had been married for over 25 years and raising six children: Bobby, Jeremiah, Sammy, Sarah, A'keiba (eventually spending some time at college) and nephew Jamaris; along with his cousin Marv co-starring.  After Hammer's personal superstar status, he wanted to involve his entire family with him for this project.  Hammer served as one of the executive producers for the show.  The series premiered June 14, 2009, airing on Sundays at 10 PM EST.  For the first season, 11 episodes and a bonus 12th were ordered.  Webisodes can still be viewed on the network's website.

As an actor, he played the role of Captain Richard "Dick" Hammer in the first season of the Jack Webb produced television show "Emergency! ", which debuted on January 15, 1972.  He left the show midway through the first season, because he felt that being a real life firefighter was more rewarding than playing a fictional one.  He returned to the LACoFD and retired with the rank of Captain.  Hammer also portrayed the Marlboro Man in cigarette advertisements in the 1970s.  He died in Long Beach from prostate cancer at the age of 69.  Hammer's grandson is the current University of Southern California starting quarterback, Sam Darnold.
