Context paragraphs:
Kidnapping, Caucasian Style: Kidnapping, Caucasian Style (Russian: Кавказская пленница ) is a 1967 Soviet comedy film dealing with a humorous plot revolving around bride kidnapping, an old tradition that used to exist in certain regions of the Northern Caucasus.

Authority figures in comedy: A recurring theme in the literary, theatrical and film tradition of comedy is the use of stock characters representing authority figures, designed to poke fun at officialdom by showing that its members are not immune to entanglement in the ridiculous.  This is an old tradition, well illustrated in works such as Chaucer's Canterbury Tales and Voltaire's "Candide".

Natalya Varley: Natalya Varley (Russian: Наталья Владимировна Варлей , born June 22, 1947) is a Soviet and Russian film and theater actress, who became famous in 1966 for her part in the comedy "Kidnapping, Caucasian Style".  In 1989 she was designated as a Meritorious Artist of RSFSR.

Russia and the United Nations: Russia succeeded the Soviet Union's seat, including its permanent membership on the Security Council in the United Nations after the dissolution of the Soviet Union in 1991.  The succession was supported by the USSR's former members and was not objected to by the UN membership; Russia accounted for about half the Soviet Union's economy and most of its land mass; in addition, the history of the Soviet Union began in Russia.  If there was to be a successor to the Soviet seat on the Security Council among the former Soviet republics, these factors made Russia seem like a logical choice.  Nonetheless, due to the rather inflexible wording of the United Nations Charter and its lack of provision for succession, the succession's technical legality has been questioned by some international lawyers.

Old Library, West Chester: The Old Library at West Chester University in West Chester, Pennsylvania, USA, is on the prominent corner of South Church Street and West Rosedale Avenue, marking the southwest corner of the Quad.

The Department of Anthropology and Sociology, and the Institute for International Development are housed in this facility.

The Firemen's Ball: The Fireman's Ball (or The Firemen's Ball, Czech: "Hoří, má panenko" ) is a 1967 comedy film directed by Miloš Forman.  It is set at the annual ball of a small town's volunteer fire department, and the plot portrays the series of disasters that occur during the evening.  The film uses few professional actors – the firemen portrayed are primarily played by the firemen of the small town where it was filmed.  In its portrayal of the prevailing corruption of the local community, and the collapse even of well-intentioned plans, the film has widely been interpreted as a satire on the East European Communist system, and it was "banned forever" in Czechoslovakia following the Soviet invasion of 1968.

United States in the Korean War: At the conclusion of World War II the Allied nations began the process of disarmament of Axis controlled regions.  Japan occupied Korea at this time and had been in control since 1910.  In 1945, the decision was made to have American Marines forces oversee Japanese surrender and disarmament south of the 38th parallel and the Soviet Union would facilitate the change of power to the north.  At the time there was no political motivation and seemed to be a logical and convenient plan of action.  The original agreement and intent was to create a unified and independent Korea out of the post Japanese occupation era.  Instead each side of the 38th parallel established its own government under the influence of the occupational country; the United States in South Korea and the Soviet Union in North Korea.  Both new Korean governments discredited the other and claimed to be the only legitimate political system.  Tensions between the North and South escalated and each side began to petition foreign powers for resources and support.  South Korea wanted weapons and supplies from Truman and the United States government while North Korea sought help from Stalin and the Soviet Union.  The United States was still war weary from the disruptive World War II campaign and refused South Korea's request for weapons and troops.  North Korea convinced the Soviet Union to supply them with the weapons and support they requested.  This decision coincided with the United States withdrawing the last remaining combat troops from South Korea.  North Korea saw its opportunity and attacked South Korean forces at the 38th parallel on June 25, 1950 and thus initiating the Korean War.

Greek dances: Greek dance ("horos") is a very old tradition, being referred to by authors such as Plato, Aristotle, Plutarch and Lucian.  There are different styles and interpretations from all of the islands and surrounding mainland areas.  Each region formed its own choreography and style to fit in with their own ways.  For example, island dances have more of a different smooth flow to them, while Pontic dancing closer to Black Sea, is very sharp.  There are over 10,000 traditional dances that come from all regions of Greece.  There are also pan-Hellenic dances, which have been adopted throughout the Greek world.  These include the syrtos, kalamatianos, pyrrhichios, hasapiko and sirtaki.

Natalya Yermolovich: Natalya Yermolovich (Belarusian: Натальля Ермаловіч ; Russian: Наталья Ермолович ; born April 29, 1964 in Homel, Belarus) is a retired female javelin thrower who represented the Soviet Union at the 1988 Summer Olympics.  She was born Natalya Kalenchukova.  Yermolovich set her personal best (69.86 metres) in 1985.

Evil empire: The phrase evil empire was first applied to the Soviet Union in 1983 by U.S. President Ronald Reagan, who took an aggressive, hard-line stance that favored matching and exceeding the Soviet Union's strategic and global military capabilities, in calling for a rollback strategy that would, in his words, "write the final pages of the history of the Soviet Union."  The characterization demeaned the Soviet Union and angered Soviet leaders.  According to G. Thomas Goodnight, the "Evil Empire" speech along with the "Zero Option" and "Star Wars" speeches represented the rhetorical side of the United States' escalation of the Cold War.  In the former, Reagan depicted nuclear warfare as an extension of the "age old struggle between good and evil", while arguing that an increased nuclear inventory as well as progress in science and technology were necessary to prevent global conflict.  Through these speeches, the Reagan administration used rhetoric to reshape public knowledge about and attitudes toward nuclear warfare.
