Sir William Connolly CBE (born 24 November 1942) is a Scottish artist, musician, presenter, actor, and retired stand-up comedian. He is sometimes known, especially in his homeland, by the Scots nickname The Big Yin ("The Big One"). Known for his idiosyncratic and often improvised observational comedy, frequently including profanity, Connolly is regarded as one of the greatest and most influential stand-up comedians of all time, having topped many polls conducted in the United Kingdom.

Connolly's trade, in the early 1960s, was that of a welder (specifically a boilermaker) in the Glasgow shipyards, but he gave it up towards the end of the decade to pursue a career as a folk singer. He first sang in the folk rock band The Humblebums with Gerry Rafferty and Tam Harvey, with whom he stayed until 1974, before beginning singing as a solo artist. In the early 1970s, Connolly made the transition from folk singer with a comedic persona to fully-fledged comedian, for which he is now best known. In 1972, he made his theatrical debut, at the Cottage Theatre in Cumbernauld, with a revue called Connolly's Glasgow Flourish. He also played the Edinburgh Festival Fringe. In 1972, Connolly's first solo album, Billy Connolly Live!, was produced, with a mixture of comedic songs and short monologues.

As an actor, Connolly has appeared in such films as Indecent Proposal (1993), Pocahontas (1995), Muppet Treasure Island (1996), Mrs Brown (1997) (for which he was nominated for the BAFTA Award for Best Actor in a Leading Role), The Boondock Saints (1999), The Last Samurai (2003), Lemony Snicket's A Series of Unfortunate Events (2004), The X-Files: I Want to Believe (2008), Brave (2012), and The Hobbit: The Battle of the Five Armies (2014). On his 75th birthday in 2017, three portraits of Connolly were made by leading artists Jack Vettriano, John Byrne, and Rachel Maclean. These were later turned into part of Glasgow's official mural trail. In October that year, he was knighted at Buckingham Palace by Prince William, for services to entertainment and charity.

Connolly announced his retirement from comedy in 2018, and in recent years he has established himself as an artist. In 2020, he unveiled the fifth release from his Born On A Rainy Day collection in London, followed by another instalment later that year. During the filming of the ITV documentary Billy Connolly: It's Been a Pleasure, he described how art had given him "a new lease of life".

He is the proprietor of The Fat Duck in Bray, Berkshire, a three Michelin star restaurant which is widely regarded as one of the best in the world.

The general format of each episode is the premise that Grylls is left stranded in a region with his film crew. The episode documents his efforts to survive and find a way back to civilization, usually requiring an overnight shelter of some kind. There are mostly wild terrains – jungles, forests, or similar non-urban areas. But in special episodes, like that in Shipyard Gdynia, there are industry areas located in cities. Grylls also tells about successful and failed survivals in the particular area which he is in.

Each episode takes about 7-10 days to shoot. Before each show the crew does about a week of reconnaissance, followed by Grylls doing a flyover of the terrain. Grylls then undergoes two days of intensive survival briefings, followed by a cameraman and a sound engineer. The directors oversee location filming and the final edit of each program. Grylls is specifically credited as "Presenter" to highlight his role in presenting survival techniques to the viewer.

Miami Ink is an American reality show on TLC that follows the events that took place at a tattoo shop in Miami Beach, Florida. The show premiered in July 2005 and finished broadcasting its sixth and final season in 2008. The show led to several spin-offs, including the shows LA Ink, London Ink, NY Ink, and Madrid Ink, most of which were also broadcast on TLC.

MythBusters is an Australian-American science entertainment television program created by Peter Rees and produced by Australia's Beyond Television Productions. The series premiered on the Discovery Channel on January 23, 2003. It was broadcast internationally by many television networks, including SBS Australia (first-run episodes, with repeat episodes shown on 7mate Australia), and other Discovery channels worldwide. The show's original hosts, special effects experts Adam Savage and Jamie Hyneman, used elements of the scientific method to test the validity of rumors, myths, movie scenes, adages, Internet videos, and news stories. The show was one of the most popular on Discovery Channel, being preceded only by How It's Made and Daily Planet, both in Canada.

Filmed in San Francisco and edited in Artarmon, New South Wales, MythBusters aired 282 total episodes before its cancellation at the end of the 2016 season in March. Planning and some experimentation took place at Hyneman's workshops in San Francisco; experiments requiring more space or special accommodations were filmed on location, typically around the San Francisco Bay Area and other locations in northern California, going to other states or even countries on occasion when required.

During the second season, members of Savage's and Hyneman's behind-the-scenes team were organized into a second team of MythBusters ("The Build Team"). They generally tested myths separately from the main duo and operated from another workshop. This arrangement continued until August 2014, when it was announced at the end of "Plane Boarding" that Tory Belleci, Kari Byron, and Grant Imahara would be leaving the show. Savage and Hyneman subsequently hosted the final two seasons alone. On October 21, 2015, it was announced that MythBusters would air its 14th and final season in 2016. The show aired its final episode with the original cast on March 6, 2016.

On November 15, 2017, sister network Science Channel revived the series with the new hosts Jon Lung and Brian Louden, who were selected via the competition spin-off MythBusters: The Search. It is now filmed in Santa Clarita and on location in other parts of southern California.

MythBusters refers to both the name of the program and the cast members who test the experiments.

The swimsuit issue was invented by Sports Illustrated editor Andre Laguerre to fill the winter months, a typically slow point in the sporting calendar. He asked fashion reporter Jule Campbell to go on a shoot to fill space, including the cover, with a beautiful model. The first issue, released in 1964, entailed a cover featuring Babette March and a five-page layout. Campbell soon became a powerful figure in modeling and molded the issue into a media phenomenon by featuring "bigger and healthier" California women and printing the names of the models with their photos, beginning a new supermodel era. In the 1950s, a few women appeared on the cover of Sports Illustrated, but the 1964 issue is considered to be the beginning of the current format known as the Swimsuit Issue. The issue that got the most letters was the 1978 edition. In 1997, Tyra Banks was the first black woman on the cover. Since 1997, the swimsuit issue has been a stand-alone edition, separate from the regular weekly magazine. Its best selling issue was the 25th Anniversary Issue with Kathy Ireland on the cover in 1989.

Through the years, many models, such as Cheryl Tiegs, Christie Brinkley, Paulina Porizkova, Elle Macpherson, Rachel Hunter, Rebecca Romijn, Petra Nemcova, Valeria Mazza, Heidi Klum, Tyra Banks, Marisa Miller, Irina Shayk, and Camille Kostek have been featured on the cover. Other models within its pages, but not on its cover, include Cindy Crawford, Stephanie Seymour, Niki Taylor, Angie Everhart, and Naomi Campbell. The eight models featured on the cover of the 2006 issue were featured in a coffee-table book called Sports Illustrated: Exposure. Photographed by Raphael Mazzucco and produced by Diane Smith, the unprecedented "reunion shoot" featured 139 pages of previously-unpublished images. In 2006, the issue expanded publishing to handheld devices. In 2007, the swimsuit issue first became available in China.

Valentina Sampaio became the swimsuit issue's first openly transgender model in 2020.

Alligator season in Louisiana begins on the first Wednesday in September and lasts for 30 days. In this time, many of the alligator hunters, following a tradition dating back about 300 years, earn most of their yearly income in a high risk vocation dependent on experience and the whims of weather within strict regulation by wildlife laws. Hunters are each issued a certain number of tags that must be attached to their kills; once they "tag out" (run out of tags), their season is over, and they may no longer kill any more alligators for the rest of the season. During this 30-day window, some of these hunters earn most of their annual income culling alligators; therefore, the ultimate goal for the alligator hunters is to tag out before the season ends. Most of the hunters spend the rest of the year harvesting other species (fish, crawfish, shrimp, crabs, raccoons, turtles, etc.) to augment their yearly incomes and/or holding down full-time jobs in other industries.

Each season, the series focuses on various teams of alligator hunters. Some episodes also feature other aspects of the social and sporting life of the swamp, including fishing and hunting for other animals.

Beginning with the fourth season, the program expanded to venues outside the Atchafalaya River Basin, featuring gator hunting crews in other parts of Louisiana, as well as the swamplands of Texas.

The Crocodile Hunter is a wildlife documentary television series that was hosted by Steve Irwin and his wife, Terri.

The series was presented on Animal Planet, becoming the network's highest-rated series at the time, and was in international syndication on networks worldwide. The series aired 64 episodes during five seasons, from 1997 through 2004, with a pilot episode in 1996 and 13 specials into 2007; with a nearly 11-year run, the series is the second longest-running program of any Discovery Communications network, behind MythBusters.

The worst-case scenario is "[o]ne of the most commonly used alternative scenarios". A risk manager may request "a conservative risk estimate representing a worst-case scenario" in order to determine the latitude they may exercise in planning steps to reduce risks. Generally, a worst-case scenario "is settled upon by agreeing that a given worst case is bad enough. However, it is important to recognize that no worst-case scenario is truly without potential nasty surprises". In other words, '[a] "worst-case scenario" is never the worst case', both because situations may arise that no planner could reasonably foresee, and because a given worst-case scenario is likely to consider only contingencies expected to arise in connection with a particular disaster. The worst-case scenario devised by a seismologist might be a particularly bad earthquake, and the worst-case scenario devised by a meteorologist might be a particularly bad hurricane, but it is unlikely that either of them will devise a scenario where a particularly bad storm occurs at the same time as a particularly bad earthquake.

The definition of a worst-case scenario varies by the field to which it is being applied. For example, in environmental engineering", "[a] worst-case scenario is defined as the release of the largest quantity of a regulated substance from a single vessel or process line failure that results in the greatest distance to an endpoint". In this field, "[a]s in other fields, the worst-case scenario is a useful device when low probability events may result in a catastrophe that must be avoided even at great cost, but in most health risk assessments, a worst-case scenario is essentially a type of bounding estimate". In computer science, the best, worst, and average case of a given algorithm express what the resource usage is at least, at most and on average, respectively. For many individuals, a worst case scenario is one that would result in their own death.
