A Cock and Bull Story (marketed in Australia, New Zealand and the United States as Tristram Shandy: A Cock and Bull Story) is a 2005 British comedy film directed by Michael Winterbottom.
 It is a film-within-a-film, featuring Steve Coogan and Rob Brydon playing themselves as egotistical actors during the making of a screen adaptation of Laurence Sterne's 18th century metafictional novel "Tristram Shandy".
 Gillian Anderson and Keeley Hawes also play themselves in addition to their "Tristram Shandy" roles.
 Since the book is about a man attempting but failing to write his autobiography, the film takes the form of being about failing to make the film.
More Die of Heartbreak is a 1987 novel by the American author Saul Bellow, and was his tenth novel.
 Like most of Bellow's other works, "More Die of Heartbreak" is grounded more in the development of character than in the growth of action.
 Among its themes are the difficulties of reconciling one's ideals with "the actual" and the difficulties of relating to parents and to mortality.
 The protagonist of the novel, Kenneth Trachtenberg, is an intellectually gifted and philosophically tortured man attempting to work out his fate and worldview.

 A putative father is a man whose biological relationship to a child is alleged but has not been established.
 A mother's boyfriend is a man whose girlfriend has a son or daughter from a previous marriage or relationship.

The Damned Crew, or Cursed Crew, was a group of young gentlemen in late 16th and early 17th century London noted for habitually swaggering drunk through the streets, assaulting passers-by and watchmen.
 The earliest certain reference to such a group appears in a sermon preached by Stephen Gosson at St Paul's Cross on 7 May 1598, when he claimed that a gang of roisterers of that name – “menne without feare, or feeling, eyther of Hell or Heauen, delighting in that title” – had all been drowned together when the boat in which they were sailing down the Thames had been upset near Gravesend.
 Another, possibly earlier reference, is in the work of the pamphleteer Thomas Nashe, who in 1592 described a vain young man attempting to give himself an air of singularity by wearing his hat pulled low over his eyes “like one of the cursed crue”.
Modesty, coming from the Latin root modestus which means "keeping within measure", and demureness is a mode of dress and deportment which intends to avoid encouraging of sexual attraction in others.
 Standards of modesty are culturally and context dependent and vary widely.
 In this use, it may be considered inappropriate or immodest to reveal certain parts of the body.
 In some societies, modesty may involve women covering their bodies completely and not talking to men who are not immediate family members; in others, a fairly revealing but one-piece bathing costume is considered modest when other women wear bikinis.
 In some countries, exposure of the body in breach of community standards of modesty is also considered to be public indecency, and public nudity is generally illegal in most of the world and regarded as indecent exposure.
 For example, Stephen Gough a lone man attempting to walk naked from south to north Britain was repeatedly imprisoned.
 However, nudity is at times tolerated in some societies; for example, during a World Naked Bike Ride.
The Collector is a Canadian supernatural drama television series about a man attempting to help save people who have bargained their souls with the Devil.
