Context paragraphs:
The Nine Tiny Piglets: The Nine Tiny Piglets are characters in the Oz series.  They first appear in "Dorothy and the Wizard in Oz", owned by the Wizard of Oz and used for a trick in which he uses sleight of hand to make it appear as if he is pulling apart the piglets to make them appear, and pushing them together again to make them disappear.  He uses this trick to deceive the Mangaboos.

Nearest neighbour distribution: In probability and statistics, a nearest neighbor function, nearest neighbor distance distribution, nearest-neighbor distribution function or nearest neighbor distribution is a mathematical function that is defined in relation to random mathematical objects known as point processes, which are types of stochastic processes often used as mathematical models of physical phenomena representable as randomly positioned points in time, space or both.  More specifically, nearest neighbor functions are defined with respect to some point in the point process as being the probability distribution of the distance from this point to its nearest neighboring point in the same point process, hence they are used to describe the probability of another point existing within some distance of a point.  A nearest neighbor function can be contrasted with a spherical contact distribution function, which is not defined in reference to some initial point but rather as the probability distribution of the radius of a sphere when it first encounters or makes contact with a point of a point process.

Peter Capaldi: Peter Dougan Capaldi (born 14 April 1958) is a Scottish actor, writer and director, best known for playing the twelfth incarnation of the Doctor in "Doctor Who" and as spin doctor Malcolm Tucker in "The Thick of It", for which he has received four British Academy Television Award nominations, winning Best Male Comedy Performance in 2010.

Mark Curry (actor): Marcus G. Curry (born June 1, 1961), known professionally as Mark Curry is an American actor, comedian, and host.  Curry is best known for his role as Mark Cooper, ex–basketball player turn teacher on the ABC sitcom "Hangin' with Mr. Cooper" which originally aired from 1992 to 1997.  Curry also served as one of the various hosts of the syndicated series "It's Showtime at the Apollo" during the early–1990s.  Curry starred in Nick At Nite's first-ever original live-action family comedy series, "See Dad Run", as Scott Baio's best friend Marcus from 2012–2015.

Polyglyphanodontia: Polyglyphanodontia is an extinct clade of lizards from the Cretaceous that includes around a dozen genera.  Polyglyphanodontians were the dominant group of lizards in North America and Asia during the Late Cretaceous.  Most polyglyphanodontians are Late Cretaceous in age, though the oldest one, "Kuwajimalla kagaensis", is known from the Early Cretaceous (Valanginian to Hauterivian) Kuwajima Formation (Japan).  Early Cretaceous South American taxon "Tijubina", and possibly also "Olindalacerta", might also fall within Polyglyphanodontia or be closely allied to the group, but if so, they would be the only known Gondwanan examples of an otherwise Laurasian clade.  They produced a remarkable range of forms.  Chamopsiids, including "Chamops", were characterized by large, blunt, crushing teeth, and were most likely omnivores. " Macrocephalosaurus", from the Gobi Desert, was a specialized herbivore; it grew to roughly a meter long and had multicusped, leaf-shaped teeth like those of modern iguanas. " Polyglyphanodon", from the Maastrichtian of Utah, was another herbivore, but its teeth formed a series of transverse blades, similar to those of "Trilophosaurus". " Peneteius" had remarkable, multicusped teeth, similar to those of mammals.  The polyglyphanodontids first appear in the latter part of the Early Cretaceous in North America, and became extinct during the Cretaceous-Paleogene extinction event.  Polyglyphanodontians closely resembled the teiid lizards, and purported teiid lizards from the Late Cretaceous appear to be polyglyphanodontians.

Changing tones: In music, changing tones (also called double neighboring tones and neighbor group) consists of two consecutive non-chord tones.  The first moves in one direction by a step from a chord tone, then skips by a third in the opposite direction to another non-chord tone, and then finally resolves back to the original chord tone.  Changing tones appear to resemble two consecutive neighbor tones; an upper neighbor and a lower neighbor with the chord tone missing from the middle.  The changing tone functions as a way to decorate, or embellish, a chord tone and are also used to provide rhythmic interest between common tones.  In rare instances, changing tones can be heard as musical cryptograms, such as the cruciform melody.

Paddington Bear: Paddington Bear is a fictional character in children's literature.  He first appeared on 13 October 1958 in the children's book "A Bear Called Paddington" and has been featured in more than twenty books written by English author Michael Bond and illustrated by Peggy Fortnum and other artists.  The friendly bear from deepest, darkest Peru—with his old hat, battered suitcase (complete with a secret compartment, enabling it to hold more items than it would appear to), duffel coat and love of marmalade—has become a classic character from English children's literature.  Paddington books have been translated into 30 languages across 70 titles and sold more than 30 million copies worldwide.  A much loved fictional character in British culture, a Paddington Bear soft toy was chosen by British tunnellers as the first item to pass through to their French counterparts when the two sides of the Channel Tunnel were linked in 1994.

Vampets: In the Cirque Du Freak series, also known as The Saga of Darren Shan by Darren Shan, Vampets are mentioned as assistants to the Vampaneze, while Vampirites (introduced later in the series) are assistants to the Vampires.  Vampets are human and noted for the tattooed V's on their heads.  In the series, Vampets are quite the opposite of the vampirites and appear to be a large nuisance to the vampires.  They also do not obey the same rules as Vampaneze therefore allowing them to use firearms.  Vampets are first mentioned in the book Hunters of the Dusk and first appear in "Allies of the Night" and continue to "Sons of Destiny".

Bear Mountain (ski area): Bear Mountain, formerly Goldmine Mountain, is a ski area in Southern California.  When its neighbor, Snow Summit, bought Bear Mountain in 2002, the new entity, Big Bear Mountain Resorts, comprised the two, with a single lift ticket usable at both.  Snow Summit's Richard "Dick" Kun led the move to focus Bear Mountain upon the snowboarder, to draw her away from Snow Summit, and thereby attune it once more to the culture of the dedicated skier.  Bear Mountain acquired the nickname, "The Park," because most of it comprises irregular terrain.  The mountain contains one of the few Superpipes in Southern California.  Given sufficient natural snow, its tree runs are open for skiing and snowboarding, unlike those at Snow Summit.  Even that territory normally "out of bounds" off of Chair 8 has opened after heavy snow.  Olympic Gold Medalist Shaun White frequented Bear Mountain while he was quite young, although he spent most of his time on the Snow Summit Westridge freestyle run.  Bear Mountain popularized freestyle skiing and snowboarding with its establishment of the first freestyle park in the early 1990s.  In the early 2000s, Transworld Snowboarding Magazine placed Bear Mountain among its Top 10 Parks.  The movement of jibing continues to grow with the addition of the Red Bull Plaza and weekly film series called “Sunday in the Park.”
