Cesar Millan, (born César Millán Favela; August 27, 1969) is a Mexican-born American dog trainer. A self-taught expert, he is widely known for his television series The Dog Whisperer with Cesar Millan, now in its eighth season and broadcast in more than eighty countries worldwide. Prior to The Dog Whisperer series, Millan focused on rehabilitating especially aggressive dogs and founded the Dog Psychology Center in South Los Angeles (2002–2008) — under construction in a new Los Angeles location as of late 2009.

Millan's first three books, including Cesar's Way, all became New York Times best sellers, have cumulatively sold two million copies in the United States, and are available in 14 other countries. In 2009, in conjunction with IMG, Millan introduced a monthly magazine also titled Cesar's Way — with The Wall Street Journal reporting at that time that half of American consumers recognized Millan. With Ilusión Millan, his former wife, he founded the Cesar and Ilusión Millan Foundation — since renamed the Millan Foundation. He is working with Yale University to create a children's curriculum based on his work.

James Augustine Aloysius Joyce (2 February 1882 – 13 January 1941) was an Irish novelist and poet, considered to be one of the most influential writers in the modernist avant-garde of the early 20th century. Joyce is best known for Ulysses (1922), a landmark work in which the episodes of Homer's Odyssey are paralleled in an array of contrasting literary styles, perhaps most prominently the stream of consciousness technique he perfected. Other major works are the short-story collection Dubliners (1914), and the novels A Portrait of the Artist as a Young Man (1916) and Finnegans Wake (1939). His complete oeuvre includes three books of poetry, a play, occasional journalism, and his published letters.

Joyce was born to a middle class family in Dublin, where he excelled as a student at the Jesuit schools Clongowes and Belvedere, then at University College Dublin. In his early twenties he emigrated permanently to continental Europe, living in Trieste, Paris and Zurich. Though most of his adult life was spent abroad, Joyce's fictional universe does not extend beyond Dublin, and is populated largely by characters who closely resemble family members, enemies and friends from his time there; Ulysses in particular is set with precision in the streets and alleyways of the city. Shortly after the publication of Ulysses he elucidated this preoccupation somewhat, saying, "For myself, I always write about Dublin, because if I can get to the heart of Dublin I can get to the heart of all the cities of the world. In the particular is contained the universal."

Mr. Bean is a British comedy television programme series of 14 half-hour episodes written by and starring Rowan Atkinson as the title character. Different episodes were also written by Robin Driscoll, Richard Curtis and one by Ben Elton. The pilot episode was broadcast on ITV on 1 January 1990, with the last television episode, "Goodnight Mr. Bean" broadcast on 31 October 1995. The final episode, "Hair by Mr. Bean of London", was a video exclusive released on 15 November 1995, but not broadcast in the UK until 2006.

Based on a character originally developed by Atkinson while he was studying for his master's degree at Oxford University, the series follows the exploits of Mr. Bean, described by Atkinson as "a child in a grown man's body", in solving various problems presented by everyday tasks and often causing disruption in the process. Bean rarely speaks, and the largely physical humour of the series is derived from his interactions with other people and his unusual solutions to situations. The series was influenced by physical performers such as Jacques Tati and comic actors from silent films.
