Gilbert and Sullivan references often appear in "The West Wing". Some incidents include an episode-long argument over whether "He is an Englishman" is from "H.M.S. Pinafore" or "The Pirates of Penzance", after one character's invocation of "duty," in the episode "And It's Surely to Their Credit"; President Bartlet's gift of a CD of "The Yeomen of the Guard" to his aide Charlie in "Stirred"; references to "The Pirates of Penzance" in "Mandatory Minimums" and "Inauguration, Part I"; and an excerpt from "A Wand'ring Minstrel I" in "A Change Is Gonna Come". Character Sam Seaborn, the Deputy Communications Director, is the former recording secretary of the Princeton Gilbert and Sullivan Society. Creator Aaron Sorkin has stated that the characters' love for Gilbert and Sullivan is part of his attempt to avoid referring to current political and entertainment personalities and to set it in a "parallel universe."
