The show's popularity led it to become a major aspect of popular culture. The show is parodied in "The Simpsons" season eight episode "The Springfield Files", which aired on January 12, 1997. In it, Mulder and Scully—voiced by Duchovny and Anderson—are sent to Springfield to investigate an alien sighting by Homer Simpson, but end up finding no evidence other than Homer's word and depart. Cigarette Smoking Man appears in the background when Homer is interviewed and the show's theme plays during one particular scene. Nathan Ditum from "Total Film" ranked Duchovny and Anderson's performances as the fourth-best guest appearances in "The Simpsons" history. In the "" episode "Trials and Tribble-ations", Benjamin Sisko is interviewed by Federation Department of Temporal Investigations agents Dulmer and Lucsly, anagrams of Mulder and Scully, respectively. The pair were later expanded upon in Christopher L. Bennett's book "Watching the Clock". "The X-Files" has also been parodied or referenced in countless other shows, like: "3rd Rock from the Sun", "Archer", "NewsRadio", "American Horror Story", "The Big Bang Theory", "Bones", "Breaking Bad", "Californication", "Supernatural", "Castle", "Family Guy", "Hey Arnold!", "King of the Hill", "South Park", and "Two and a Half Men". Welsh music act Catatonia released the 1998 single "Mulder and Scully", which became a hit in the United Kingdom. American singer and songwriter Bree Sharp wrote a song called "David Duchovny" about the actor in 1999 that heavily references the show and its characters. Although never a mainstream hit, the song became popular underground and gained a cult following. Finnish band Sonata Arctica released, in 1999, the song "Letter to Dana", in which the title character, Dana O'Hara, is named after Scully. The series has also been referenced in: "The Bad Touch" by the Bloodhound Gang, "A Change" by Sheryl Crow, "Year 2000" by Xzibit, and "One Week" by Barenaked Ladies.
