Krulwich received his bachelor's degree in U.S. history from Oberlin College in 1969 and his Juris Doctor degree from Columbia Law School in 1974. Just two months later, he abandoned his pursuit of a law career to cover the Watergate hearings for Pacifica Radio. In 1976, he became Washington bureau chief for Rolling Stone.

The word asshole, a variant of arsehole, which is still prevalent in British and Australian English, is a vulgar to describe the anus, often pejoratively used to refer to people.

The word arse in English derives from the Germanic root *arsaz, which originated from the Proto-Indo-European root *ors — meaning buttocks or backside. The combined form arsehole is first attested from 1500 in its literal use to refer to the anus. The metaphorical use of the word to refer to the worst place in a region, e.g., "the arsehole of the world") is first attested in print in 1865; the use to refer to a contemptible person is first attested in 1933. In the ninth chapter of his 1945 autobiography, Black Boy, Richard Wright quotes a snippet of verse that uses the term: "All these white folks dressed so fine / Their ass-holes smell just like mine ...". Its first appearance as an insult term in a newspaper indexed by Google News is in 1965. As with other vulgarities, these uses of the word may have been common in oral speech for some time before their first print appearances. By the 1970s, Hustler magazine featured people they did not like as "Asshole of the Month." In 1972, Jonathan Richman's Modern Lovers recorded his song "Pablo Picasso," which includes the line "Pablo Picasso was never called an asshole."

Oliver Wolf Sacks, CBE (born 9 July 1933, London, England), is a British neurologist, psychologist, writer, and amateur chemist who has spent the major portion of his career in the United States. He lives in New York City, and is professor of neurology and psychiatry at Columbia University, where he also holds the position of "Columbia Artist". He previously spent many years on the clinical faculty of Yeshiva University's Albert Einstein College of Medicine.

Sacks is the author of numerous bestselling books, including several collections of case studies of people with neurological disorders. His 1973 book Awakenings was adapted into an Academy Award-nominated film of the same name in 1990 starring Robin Williams and Robert De Niro. He, and his book Musicophilia: Tales of Music and the Brain, were the subject of "Musical Minds", an episode of the PBS series Nova.

Sacks was the youngest of four children born to a North London Jewish couple: Samuel Sacks, a physician (died June 1990), and Muriel Elsie Landau, one of the first female surgeons in England. Sacks had a large extended family, and among his first cousins are Israeli statesman Abba Eban, writer and director Jonathan Lynn, and economist Robert Aumann.

Saddam Hussein Abd al-Majid al-Tikriti (Arabic: صدام حسين عبد المجيد التكريتي Ṣaddām Ḥusayn ʿAbd al-Maǧīd al-Tikrītī; 28 April 1937 – 30 December 2006) was the fifth President of Iraq, serving in this capacity from 16 July 1979 until 9 April 2003. A leading member of the revolutionary Arab Socialist Ba'ath Party, and later, the Baghdad-based Ba'ath Party and its regional organisation Ba'ath Party – Iraq Region, which espoused ba'athism, a mix of Arab nationalism and Arab socialism, Saddam played a key role in the 1968 coup, later referred to as the 17 July Revolution, that brought the party to long-term power of Iraq.

As vice president under the ailing General Ahmed Hassan al-Bakr, and at a time when many groups were considered capable of overthrowing the government, Saddam created security forces through which he tightly controlled conflict between the government and the armed forces. In the early 1970s, Saddam nationalized oil and other industries. The state-owned banks were put under his control, leaving the system eventually insolvent mostly due to the Iran–Iraq War, the Gulf War, and UN sanctions. Through the 1970s, Saddam cemented his authority over the apparatuses of government as oil money helped Iraq's economy to grow at a rapid pace. Positions of power in the country were filled with Sunnis, a minority that made up only a fifth of the population.
