George Lorimer (rugby league): George Lorimer (birth registered April→June 1872 — 8 February 1897 (aged 24)) birth registered in Bradford district, was a professional rugby league footballer who played in the 1890s, playing club level rugby league (RL) for Manningham F.C., as a fullback , i.e. number 1, he died of Typhoid fever in Bradford district, his funeral took place at Heaton Baptist Church, hundreds of people walked alongside the horse-drawn hearse, and an estimated 8,000 people lined the streets from Manningham to Heaton.  Prior to Tuesday 27 August 1895, Manningham was a rugby union club, it then became a rugby league club, and since Friday 29 May 1903 it has been the association football (soccer) club Bradford City A.F.C..

Storage pit (archaeology): Storage pits were underground cists used by many people in the past to protect the seeds for the following year's crops and surplus food from being eaten by insects and rodents.  The underground pits were sometimes lined and covered, for example with slabs of stone and bark and tightly sealed with adobe.

Sexuality after spinal cord injury: Although spinal cord injury (SCI) often causes sexual dysfunction, many people with SCI are able to have satisfying sex lives.  Physical limitations acquired from SCI affect sexual function and sexuality in broader areas, which in turn has important effects on quality of life.  Damage to the spinal cord impairs its ability to transmit messages between the brain and parts of the body below the level of the lesion.  This results in lost or reduced sensation and muscle motion, and affects orgasm, erection, ejaculation, and vaginal lubrication.  More indirect causes of sexual dysfunction include pain, weakness, and side effects of medications.  Psycho-social causes include depression and altered self-image.  Many people with SCI have satisfying sex lives, and many experience sexual arousal and orgasm.  People with SCI employ a variety of adaptations to help carry on their sex lives healthily, by focusing on different areas of the body and types of sexual acts.  Neural plasticity may account for increases in sensitivity in parts of the body that have not lost sensation, so people often find newly sensitive erotic areas of the skin in erogenous zones or near borders between areas of preserved and lost sensation.

Ebenezer Floppen Slopper's Wonderful Water slides: Ebenezer Floppen Slopper's Wonderful Water slides is an abandoned waterpark located on a large hill on Roosevelt Road and Route 83 in Oakbrook Terrace, Illinois.  It first opened on July 5, 1980 with two 800 foot concrete water slides and gradually added 5 additional slides and a wading pool.  The water park became a major summer attraction for residents of surrounding towns and communities as people lined up for rides down the large winding slides.  When the two main slides first began operation, people slid down in groups of up to eight people at a time on rubber mats.  The 5 other slides added to the park included 2 flat racer slides in which people slid down head first on folded rubber mats, 2 semi enclosed tube body slides, and a smaller inner tube slide which emptied into a nearby wading pool.  The slides were also unique in that they were lined with a blue rubber foam material which would prevent injuries from contacts with the slide walls.  Due to the design of the 2 main large concrete slides, especially with the V-shaped configuration of their side walls, people could also slide quite high up the walls of the slides, especially when hitting a turn at high speeds.  Around 1987, the large concrete slides were re surfaced with flat bottoms with humps and bumps in which people went down solo on inner tubes, getting bumped up and down and sideways as they went down the renovated slides and the park was re named "Doc River's Roaring Rapids water park."

Sooners: Sooners is the name given to settlers who entered the Unassigned Lands in what is now the state of Oklahoma before the official start of the Land Rush of 1889.  President Benjamin Harrison officially proclaimed the Unassigned Lands open to settlement on April 22, 1889.  As people lined up around the borders of the Oklahoma District, they waited for the official opening.  It wasn't until noon that it officially was opened to settlement.  The name derived from the "sooner clause" of the act, which stated that anyone who entered and occupied the land prior to the opening time would be denied the right to claim land.

New Baltimore, Virginia: New Baltimore is an unincorporated community and census-designated place (CDP) in eastern Fauquier County, Virginia, United States.  The population as of the 2010 census was 8,119.  The community has existed since the early 19th century, but it has had its most significant growth since the 1980s.  It is the portion of Fauquier County with the easiest access to Washington, D.C., and as a result, many people who live in New Baltimore commute into DC.  Other major communities close to New Baltimore are Warrenton, Gainesville/Haymarket area, and Manassas.  The area officially considered to be New Baltimore expanded significantly in 2006 with Fauquier County's designation of service districts, of which New Baltimore is one.  The service district designation provides added access to utilities such as water and sewer, and targets the area for growth.

Land Rush of 1889: The Oklahoma Land Rush of 1889 was the first land rush into the Unassigned Lands.  The area that was opened to settlement included all or part of the present-day Canadian, Cleveland, Kingfisher, Logan, Oklahoma, and Payne counties of the US state of Oklahoma.  The land run started at high noon on April 22, 1889, with an estimated 50,000 people lined up for their piece of the available two million acres (8,000 km²).

Niles Canyon ghost: The Niles Canyon ghost story is the Northern California variation on the vanishing hitchhiker archetype.  There are many different variations of this story depending on whom you ask.  All stories include a girl being involved in some sort of motorized vehicle accident on February 26 (year often changed).  One variation of the story includes a girl being involved in a car crash on Niles Canyon road (off the 680 freeway in Sunol, California) on the way to her prom.  The girl died on impact and to this day is said to haunt Niles Canyon road every February 26.  The tale of the haunting goes that people traveling along Niles Canyon road (now Highway 84) on the night of February 26 will see a normal-looking high school-aged girl walking along the road in a prom dress (many people have said it is white).  People traveling along the road (mostly those traveling alone) have said to have stopped and offered the girl a ride.  She accepts the ride, giving the driver an address across the bridge (either Dumbarton or Bay Bridge depending on the storyteller).  Once the driver gets to the beginning of the bridge, the girl will disappear.  Sometimes people have gone to the address to find that a girl many years ago matching that description once lived there.  Today, many people will travel along this treacherous pitch black road in the hopes of catching a glimpse of the Niles Canyon ghost.

2002 El Ayyat railway accident: The El Ayyat train disaster happened at 02:00 on the morning of 20 February 2002 in an eleven-carriage passenger train travelling from Cairo to Luxor.  A cooking gas cylinder exploded in the fifth carriage, creating a fire which engulfed seven third-class carriages, reducing them almost to cinders.  The initial number of dead given by officials at the time was 383, all Egyptians.  However, considering that seven carriages were burnt to the ground, and each carriage was packed with at least double the maximum carrying capacity of 150, this number is considered by many people to be a great underestimate.  The dubious nature of the given death toll lies with the absence of a full passenger list; accounting for those missing was almost impossible at the time.  In addition, the fire was so intense and the carriages so badly burned that many corpses had been reduced to ash.  As there was no means of communication between the driver and the rear carriages, the driver did not know of the fire until about two hours after it had begun, resulting in many people, attempting to flee from the overcrowded carriages, jumping to their death.  Some important Egyptians have commentated that the official number of 383 dead is grossly inaccurate and was an attempt to lessen the damage done to the reputation of the government.  Many people consider a number of about 1000 deaths to be more accurate.

2005 Erbil bombing: The 2005 Erbil bombing was a suicide attack on the offices of Kurdish political parties in Erbil, Iraq, north of Baghdad on May 4, 2005.  The attacker detonated explosives strapped to his body as people lined up outside a police recruiting centre in Erbil.
