The famous Rat Pack, which includes Frank Sinatra, Sammy Davis Jr., and Dean Martin are seen here shooting pool with each other in this famous poster. It also included Peter Lawford and Joey Bishop. The term was given to the group in the 1950's by actress Lauren Bacall after she saw them come home from a night on the town. It is rumored, however, that the nickname came from Bacall's husband, Humphrey Bogart. They made a bunch of movies together, including Ocean's Eleven in 1960. That movie has since been redone in the 21st century. They often showed up at each other's shows.
