Tusks are elongated, continuously growing front teeth, usually but not always in pairs, that protrude well beyond the mouth of certain mammal species. They are most commonly canines, as with warthogs, pig, and walruses, or, in the case of elephants, elongated incisors. In most tusked species both the males and the females have tusks although the males are larger. Tusks are generally curved, though the narwhal's sole tusk is straight and has a helical structure. In the elephant, the tusks were originally second incisors. Continuous growth is enabled by formative tissues in the apical openings of the roots of the teeth.

Tusks have a variety of uses depending on the animal. Social displays of dominance, particularly among males, are common, as is their use in defence against attackers. Elephants don't use them as digging and boring tools. Walruses use them to grip on ice and to haul out on ice. The presence of tusks in only the male narwhals suggests that for these whales it is a secondary sex characteristic.

Donald Franciszek Tusk [ˈdɔnalt franˈt​͡ɕiʂɛk ˈtusk] ( listen) (born 22 April 1957) is a Polish politician who has been Prime Minister of Poland since 2007. He was a co-founder and is chairman of the Civic Platform (Platforma Obywatelska) party.

Tusk was officially designated as Prime Minister on 9 November 2007 and took office on 16 November. His cabinet won a vote of confidence in the Sejm on 24 November 2007. He is currently the longest serving prime minister of the Third Republic of Poland. In October 2011, Tusk's Civic Platform won a plurality of seats in the Polish parliamentary election, meaning that Tusk became the first Prime Minister to be re-elected since the fall of communism in Poland.

Tusk began his public career as an activist in his home town of Gdansk, supporting Solidarity and organizing his fellow university students. With the exception of one four-year stretch, Tusk has served in the Third Republic parliament almost continuously since its first elections in 1991. He was Vice Marshal (deputy speaker) of the Senate from 1997 to 2001 and Vice Marshal of the Sejm from 2001 to 2005. He also served as Leader of the Opposition from 2003 to 2007.

Nigel Paul Farage ( /ˈfærɑːʒ/, FARR-ahzh; born 3 April 1964, Farnborough, Kent), is a British politician and is the Leader of the UK Independence Party (UKIP), a position he also held from September 2006 to November 2009. He is a Member of the European Parliament for South East England and co-chairs the Eurosceptic Europe of Freedom and Democracy group.

Farage is a founding member of the UKIP, having left the Conservative Party in 1992 after they signed the Maastricht Treaty. Having unsuccessfully campaigned in European and Westminster parliamentary elections for UKIP since 1994, he gained a seat as an MEP for South East England in the 1999 European Parliament Election — the first year the regional list system was used — and was re-elected in 2004 and 2009. Farage describes himself as a libertarian and rejects the notion that he is a conservative.

In September 2006, Farage became the UKIP Leader and led the party through the 2009 European Parliament Election in which it received the second highest share of the popular vote, defeating Labour and the Liberal Democrats with over two million votes. However he stepped down in November 2009 to concentrate on contesting the Speaker John Bercow's seat of Buckingham in the 2010 general election.

Lindsey Adams Buckingham (born October 3, 1949) is an American guitarist, singer, composer and producer, most notable for being the guitarist and male lead singer of the musical group Fleetwood Mac from 1975 to 1987, and 1997 to present day.

In 2011, Buckingham was ranked 100th in Rolling Stone magazine's 2011 list of "The 100 Greatest Guitarists of All Time". In Fleetwood Mac's heyday, Buckingham was known for his finger picking guitar style and wide vocal range as well as the famous (sometimes tense) chemistry between himself and former girlfriend and fellow bandmate Stevie Nicks.

Born in Palo Alto, California, Buckingham was the third and youngest child of Rutheda (née Elliott) and Morris Buckingham. He had two older brothers, Jeff and Greg. Growing up in the San Francisco Bay Area community of Atherton, Buckingham and his brothers were encouraged to swim competitively. Though Buckingham dropped out of athletics to pursue music, his brother Greg went on to win a silver medal at the 1968 Olympics in Mexico City.
