Problem: Background: Rouvas was born on 5 January 1972 in the village of Mandoukion, near Corfu City on the island of Corfu, the eldest of four sons of Konstantinos "Kostas" Rouvas (an ambulance driver) and the teenaged Anna-Maria Panaretou (a duty-free shop clerk at the local airport). He has three brothers: Billy (b. Vasilios), Tolis (b. Apostolos, 1975) and Nikos (b. Nikolaos, 1991). The family was poor, and Rouvas began taking care of his brothers at age five. At age four, he exhibited athletic ability and took ballet classes as a child.
Context: In December 1998 Rouvas released his sixth album (the first with his new label): Kati Apo Mena (Something From Me), written by Giorgos Theofanous. "Den Ehi Sidera I Kardia Sou" ("Your Heart Doesn't Have Steel Rails") was a hit, and remains one of his most-popular songs. To promote the album Rouvas performed at the Virgin Megastore in Athens, where thousands of fans created a traffic jam. The next year, Rouvas records "Oso Exo Esena" ("As Long As I Have You"), a duet with singer Stelios Rokkos. The two artists work and perform together at Bio Bio in Athens during the summer.  In March 2000 Rouvas released his seventh album, 21os Akatallilos (21+ X-Rated), and performed with Katy Garbi at Pili Axiou in Thessaloniki. The album and its first single, "Andexa" ("I Held Out"), reached number one on the charts. During May rehearsals for summer performances Rouvas was hospitalized with abdominal pain, which was diagnosed as peritonitis and required an appendectomy. On 25 October 2000, he began appearing with Antonis Remos and Peggy Zina at Apollonas for the winter season. That year Rouvas became the Pepsi spokesperson for the company's Greek summer campaign making a first television ad, a first for a Greek entertainer. His collaboration with Pepsi continued into 2001, with a May television ad. The advertisement, featuring a semi-nude Rouvas holding a Pepsi bottle in front of his genitals, was controversial among women's rights and parental associations. Calling it "unsightly, vulgar and unacceptable", they tried to have the ad blocked as "disgrac[ing] childhood innocence and dignity." The Pepsi Tour 2001, of seven Greek cities, followed.  During summer 2000 Rouvas, Psinakis and a number of other celebrities visited Mykonos on a yacht borrowed from a local physician. They were accused of drug possession, since the yacht contained narcotics. The incident was publicized amid speculation that Rouvas might have a drug addiction. Although the doctor admitted that the narcotics were his, his guests were questioned. Wishing to avoid court, Rouvas paid a fine and minimized the incident. However, thousands of T-shirts were printed which read: "Imoun ki ego sto kotero!" ("I was on the yacht, too!").

Background: Yankovic was born in Downey, California and raised in Lynwood, California. He is the only child of Mary Elizabeth (Vivalda) and Nick Yankovic. His father was born in Kansas City, Kansas, of Yugoslavian descent, and began living in California after serving during World War II; he believed "the key to success" was "doing for a living whatever makes you happy" and often reminded his son of this philosophy. Nick married Mary in 1949.
Context: Yankovic is well known for creating parodies of contemporary radio hits, typically which make up about half of his studio releases. Unlike other parody artists such as Allan Sherman, Yankovic and his band strive to keep the backing music in his parodies the same as the original, transcribing the original song by ear and re-recording the song for the parody. In some cases, in requesting the original band to allow for his parody, the band will offer to help out with the recreation: Dire Straits members Mark Knopfler and Guy Fletcher perform on "Money for Nothing/Beverly Hillbillies*", Yankovic's parody of Dire Straits' "Money for Nothing", while Imagine Dragons provided Yankovic with advice on how to recreate some of the electronic sounds they used for "Radioactive" in Yankovic's parody "Inactive". Yankovic's career in novelty and comedy music has outlasted many of his "mainstream" parody targets, such as Toni Basil, MC Hammer, and Men Without Hats. Yankovic's continued success (including the top 10 single "White & Nerdy" and album Straight Outta Lynwood in 2006) has enabled him to escape the one-hit wonder stigma often associated with novelty music.  Although many of Yankovic's songs are parodies of contemporary radio hits, it is rare that the song's primary topic lampoons the original artist as a person, or the song itself. Most Yankovic songs consist of the original song's music, with a separate, unrelated set of amusing lyrics. Yankovic's humor normally lies more in creating unexpected incongruity between an artist's image and the topic of the song, contrasting the style of the song with its content (such as the songs "Amish Paradise", "White & Nerdy", and "You're Pitiful"), or in pointing out trends or works which have become pop culture cliches (such as "eBay" and "Don't Download This Song"). Yankovic's parodies are often satirical of popular culture, including television (see The TV Album), movies ("The Saga Begins"), and food (see The Food Album). Yankovic claims he has no intention of writing "serious" music. In his reasoning, "There's enough people that do unfunny music. I'll leave the serious stuff to Paris Hilton and Kevin Federline."  Yankovic considered that his first true satirical song was "Smells Like Nirvana", which references unintelligible lyrics in Nirvana's "Smells Like Teen Spirit". Other satirical songs include "Achy Breaky Song", which refers to the song "Achy Breaky Heart", "(This Song's Just) Six Words Long", which refers to the repetitious lyrics in "Got My Mind Set on You", and "Perform This Way", set to Lady Gaga's "Born This Way" that drew inspiration from Lady Gaga's outlandish but confident attitude.  Yankovic is the sole writer for all his songs and, for "legal and personal reasons", does not accept parody submissions or ideas from fans. There exists, however, one exception to this rule: Madonna was reportedly talking with a friend and happened to wonder aloud when Yankovic was going to turn her "Like a Virgin" into "Like a Surgeon". Madonna's friend was a mutual friend of Yankovic's manager, Jay Levey, and eventually Yankovic himself heard the story from Levey.
