Background: "Hit 'Em Up" is a diss song by rap artist 2Pac featuring his group the Outlawz. It is the B-side to the single "How Do U Want It", released on June 4, 1996. The song's lyrics contain vicious insults to several East Coast rappers, chief among them, Shakur's former friend turned rival, The Notorious B.I.G., also known as Biggie Smalls.
Context: The music video for "Hit 'Em Up" was filmed in a warehouse off Slauson Avenue near Fox Hills Mall in Los Angeles in May 1996. It was filmed by the production company Look Hear Productions. Shakur raps in a white room with The Outlawz, as well as in purple-caged room and a black room with bullet holes in the background. TV monitors in the background show clips of Shakur, Puffy, and Biggie Smalls, and even clips from the video "Made Niggaz." The video featured actors who were recalled from their prior roles in the music video for "2 of Amerikaz Most Wanted" to impersonate some of those who were attacked in "Hit 'Em Up." This included Biggie, whose stand-in stares dully into the camera and sports a Kangol and jacket, similar to one Biggie would wear. During the moments where Shakur raps about his claimed affair with Evans, the Biggie impersonator crouches near the camera while Shakur yells in his face. Puffy is also impersonated, appearing with a high-top fade and leaning towards the camera, lowering and raising his sunglasses.  During the shooting of the video, Shakur was engaged in an argument with someone, who was heard telling him "You'll get shot." His armed bodyguard assured him that he had nothing to worry about. He also broke up a fight involving his friend Muta during the filming, and fired a production assistant on set. The assistant was answering Shakur's pager and returning his personal calls without his consent. Many callers were confused or angry that a female assistant was answering Shakur's calls. The assistant had mistakenly lost the pager, and with Shakur already growing wary of her, fired her for that reason.  Like the song, the video for "Hit 'Em Up" has also been called "infamous". The pro-West Coast track's music video featured the members crushing buildings in Manhattan, which was already done in another pro-West Coast music video for "New York, New York" by Tha Dogg Pound earlier. The music video for "Hit 'Em Up" can be found on Tupac: Live at the House of Blues DVD.

Problem: Background: Arthur Antunes Coimbra (Portuguese pronunciation: [aR'tuR a'tunis ko'ibra], born 3 March 1953 in Rio de Janeiro), better known as Zico (['ziku]), is a Brazilian coach and former footballer, who played as an attacking midfielder. Often called the "White Pele", he was a creative playmaker, with excellent technical skills, vision, and an eye for goal, who is considered one of the most clinical finishers and best passers ever, as well as one of the greatest players of all time. Arguably the world's best player of the late 1970s and early 80s, he is regarded as one of the best playmakers and free kick specialists in history, able to bend the ball in all directions.
Context: After receiving offers from A.S. Roma and A.C. Milan, moving to Italy seemed right and a four-million dollar proposal from Udinese was on the table. Such amount of money made bigger clubs pressure the FIGC (Italian Football Federation) that blocked the transfer expecting financial guarantees. This caused a commotion in Udine as enraged Friulians flocked to the streets in protest against the Italian federation and the federal government. Historical reasons would make them shout "O Zico, o Austria!" ("Either Zico or Austria"). At the end of the controversy, the deal went through and though leaving Flamengo fans in sadness, Zico made the Friulians fans finally dream of better days.  In the 1983-84 Serie A, his first in Italy, his partnership with Franco Causio promised to take Udinese to a higher level, gaining respect from giants Juventus and Roma. His free kicks caused such an impact that TV sports programs would debate how to stop them. Despite his excellent performance, the club's season ended in disappointment as Udinese, in spite of scoring almost twice as many goals as the previous year, only gathered 32 points and was ninth in the final standing, losing three places in comparison to 1982-83. His personal top scoring dispute against Juventus's Michel Platini was exciting - Zico scored 19 goals, one fewer than top scorer Platini, having played 4 fewer matches than the French footballer due to an injury. Plus, he was voted 1983 Player of the Year by World Soccer Magazine.  His following season would be punctuated by injuries and suspensions for openly attacking referees. He also used to complain about the board's lack of ambition for not signing competitive players, which made the team too dependent on him. Furthermore, Italian tax officials pressed charges against him for tax evasion. Pressured, Zico delivered an amazing display against Diego Maradona's Napoli, his last match as a bianconero, and returned to Brazil and Flamengo, sponsored by a group of companies.  He became a fan favorite with his spectacular goals and is still adored now by all Udinese fans.
