How to Be a Gentleman is an American sitcom television series that originally aired on CBS from September 29, 2011, to June 23, 2012. Lead actor David Hornsby created the series, adapting the nonfiction book of the same name by John Bridges.How to Be a Gentleman received a thirteen episode order for its initial season and the series was placed on the network’s Thursday night lineup at 8:30 PM Eastern, replacing Rules of Engagement in that slot as the latter series was going to move to Saturday nights once it launched for the season. The first two episodes, however, failed to draw a high rating and were unable to hold the audience of lead in program The Big Bang Theory, which was CBS’ highest rated sitcom. On October 7, 2011, CBS cancelled the series after three low-rated episodes. They also cut the episode order from 13 to 9 episodes, which effectively ended production as the series had just finished its ninth episode when the announcement was made. CBS announced that Rules of Engagement would be retaking its former time slot shortly thereafter, with How to Be a Gentleman moving to Saturday nights.Although the reduction in episodes and move to Saturday did not officially result in the series’ cancellation, CBS finally pulled the plug after one further episode had aired after its ratings reflected a loss of half of the audience from the previous program, a rerun of Two and a Half Men. CBS later made the decision to burn off the remaining episodes on Saturday evenings over the summer, beginning on May 26.
