Context paragraphs:
Zoo Parade: Zoo Parade is an American television program broadcast from 1950 to 1957 that featured animals from the Lincoln Park Zoo in Chicago.  The program's host was Marlin Perkins, the Zoo's director.  Perkins went on to host the program "Wild Kingdom".  Jim Wehmeyer has described the show: "A precursor of sorts to the regularly featured animal segments on "The Tonight Show" and other late-night talk shows, "Zoo Parade" was a location-bound production (filmed in the reptile house basement) during which Perkins would present and describe the life and peculiarities of Lincoln Park Zoo animals."

Pattycake (gorilla): Pattycake, also known as Patty Cake (September 3, 1972 – March 31, 2013) was a female western lowland gorilla ("Gorilla gorilla gorilla") born to Lulu and Kongo at the Central Park Zoo in New York City.  She was the first baby gorilla successfully born in captivity in New York.  Months after her much publicized birth, Pattycake's arm was broken when it got stuck in her cage as her mother grabbed her away from her father.  The incident was sensationally anthropomorphized in the media as a domestic dispute between Lulu and Kongo, but in reality experts thought it was a simple accident.

Guy the Gorilla: Guy the Gorilla (1946–1978) was a western lowland gorilla ("Gorilla gorilla gorilla") who was London Zoo's famous resident, something of a celebrity in the 1960s–70s and was often profiled on children's TV shows and natural history productions.  Guy the Gorilla was one of London Zoo's best-loved animals.  The exact day of Guy's birth was never known, but the official birthday was set by the Zoo as May 30, and he received large numbers of cards every year.

Veterinary pathology: Veterinary pathologists are doctors of veterinary medicine who specialize in the diagnosis of diseases through the examination of animal tissue and body fluids.  Like medical pathology, veterinary pathology is divided into two branches, anatomical pathology and clinical pathology.  Other than the diagnosis of disease in food-producing animals, companion animals, zoo animals and wildlife, veterinary pathologists also have an important role in drug discovery and safety as well as scientific research.

Tata Steel Zoological Park: Tata Steel Zoological Park is situated in the corner most area of Jubilee Park.  This zoo is known for its Safari Park, which enables tourists to drive through the wooden area, where animals roam freely.  Tourists can also visit the Nature Education Centre in the zoo, which gives information about the zoo animals.

Killing of Harambe: On May 28, 2016, a three-year-old boy climbed into a gorilla enclosure at the Cincinnati Zoo and Botanical Garden and was grabbed and dragged by Harambe, a 17-year-old Western lowland gorilla.  Fearing for the boy's life, a zoo worker shot and killed Harambe.  The incident was recorded on video and received broad international coverage and commentary, including controversy over the choice to kill Harambe.  A number of primatologists and conservationists wrote later that the zoo had no other choice under the circumstances, and that it highlighted the danger of zoo animals in close proximity to humans and the need for better standards of care.

Gertrude Lintz: Gertrude Ada Davies Lintz (died 1968) was an English-American dog breeder and socialite known for keeping exotic animals, including chimpanzees and gorillas, in her Brooklyn home.  Her gorilla Buddy was sold to a circus and renamed Gargantua.  Her gorilla Massa was sold to the Philadelphia Zoo, eventually becoming the longest-living documented gorilla.  Her 1942 memoir "Animals Are My Hobby" inspired the 1997 American film "Buddy".  Lintz was played by Rene Russo in the film.

Deez Nuts (politician): Deez Nuts was a satirical candidate, portrayed by Brady C. Olson, who ran in the 2016 United States presidential election.  His form to run for office was filed with the Federal Election Commission in late July 2015.  In polls conducted by Public Policy Polling in Iowa, Minnesota and North Carolina in mid-August 2015, he polled at 8, 8 and 9 percent respectively, garnering the attention of the media.  On October 11, 2015, Deez Nuts announced on his Facebook page his intention to run for Speaker of the United States House of Representatives, citing his eligibility despite not being a member of the House itself and the scarcity of candidates.  A poll performed in mid-August 2016 shows Deez Nuts slightly edging out Harambe and Jill Stein in Texas, with 3% of the vote.

Limburg Zoo: The Limburg Zoo, also known as Zwartberg Zoo, was a zoo in the Belgian parish of Zwartberg in the municipality of Genk.  The zoo was private property of the Wouters family and did not receive any subsidy or sponsorship.  The zoo was known for its large number of animals, which resulted from the internal breeding programme and the acquisition of abused and dumped animals from bankrupt zoos and circuses.  The large number of animals, the poor state of the animal enclosures, and actions by animal rights organisations drew media attention to the zoo.  In 1997 the Wouters family decided to close it; the animals were relocated to other zoos.

Exotic ungulate encephalopathy: Exotic ungulate encephalopathy is a transmissible spongiform encephalopathy (TSE), or prion disease, identified in infected organs of zoo animals.  This subgroup of the TSEs in captive animals was identified in zoo animals in Great Britain including species of greater kudu, nyala, gemsbok, the common eland, Arabian and Scimitar Oryx, an Ankole-Watusi cow, and an American bison.  Studies indicate that transmission likely occurred via the consumption of feed supplemented with meat and bone meal, although some animals died after the British ban on ground offal in animal feed.  All animals died during the 1990s, with the last death occurring in 1998.
