Darwin Award: Dumbest Accidental Deaths.

A "Darwin Award" is an honor named after evolutionary theorist Charles Darwin, given for people who "do a service to humanity by accidentally removing themselves from the gene pool" (i.e. lose the ability to reproduce either by death or sterilization in a stupid fashion). According to Wendy Northcutt, author of the Darwin Award books: "TheAwards honor people who ensure the long-term survival of the human race by removing themselves from the gene pool in a sublimely idiotic fashion." Example of Darwin award winners include:
Jumping out of a plane to film skydivers without wearing a parachute (U.S., 1987); Trying to get enough light to look down the barrel of a loaded muzzleloader gun using a cigarette lighter (U.S., 1996); Attempting to play Russian roulette with a semi-automatic pistol that automatically loads the next round into the chamber.

Each year, one award is selected as being much more "honorable" than the rest, and it is crowned as the "Darwin Award of the Year". In 2007, the winner was "The Enema Within", in which a man died of alcohol poisoning after having two 1.5 litre bottles (over 100 fluid ounces) of sherry inserted anally. 

Crime Scene Cleaners Inc.

The police, the fire department and the crime-scene investigators who arrive at a crime scene perform crucial tasks in the aftermath of a violent death. But they don't, as a general rule, clean up. Mopping up after someone who dies violently is the responsibility of that person's family. Now there is a company, called Crime Scene Cleaner Inc., that can handle the dirty job, literally. It's a cleaning maintenance service specializing in the cleanup of homicide, suicide and accidental deaths. The company offers services of cleaning, disinfecting and removal of all contaminated items to restore the scene to a safe, non-biohazardous state. Link: http://www.crimescenecleaners.com/

Creepy place: Chernobyl, Pripyat, Ukraine.

Prypiat (Ukrainian: При́п’ять, Pryp”jat’; Russian: При́пять, Pripjat’), or Pripyat, is an abandoned city in the zone of alienation in northern Ukraine, Kiev Oblast, near the border with Belarus. The city was founded in 1970 to house the Chernobyl Nuclear Power Plant workers, and was abandoned in 1986 following the Chernobyl disaster. Its population had been around 50,000 prior to the accident.

It is difficult to accurately quantify the number of deaths caused by the events at Chernobyl.

 

In case you don't know:

The Chernobyl disaster was a nuclear reactor accident at the Chernobyl Nuclear Power Plant in Ukraine, then part of the Soviet Union. It is considered to be the worst nuclear power plant disaster in history and the only level 7 instance on the International Nuclear Event Scale. It resulted in a severe release of radioactivity into the environment following a massive power excursion which destroyed the reactor.
