The title refers to a method prescribed to Trumper for the treatment of non-specific urological disorders relating to his abnormally narrow urinary tract. Trumper's urologist, Dr. Jean Claude Vigneron, offers him three options for the treatment of his disorder: abstinence from sex and alcohol, a painful operation to widen the urinary canal, or the Water Method, which consists simply of consuming abnormal quantities of water before and after sex to flush bacteria out of the urinary tract. Trumper opts for the Water Method, suggesting both his generally comical cowardice and lack of self-discipline.
