My favourite one is the following:
THE 1999 DARWIN AWARD WINNER IS.....

THOMPSON, MANITOBA, CANADA. Telephone relay company night watchman
Edward Baker, 31, was killed early Christmas morning by excessive
microwave radiation exposure. He was apparently attempting to keep
warm next to a telecommunications feed-horn. Baker had been
suspended on a safety violation once last year, according to Northern
Manitoba Signal Relay spokesperson Tanya Cooke. She noted that Baker's
earlier infraction was for defeating a safety shut-off switch and
entering a restricted maintenance catwalk in order to stand in front
of the microwave dish. He had told coworkers that it was the only way
he could stay warm during his twelve-hour shift at the station, where
winter temperatures often dip to forty below zero. Microwaves can
heat water molecules within human tissue in the same way that they heat
food in microwave ovens. For his Christmas shift, Baker reportedly
brought a twelve pack of beer and a plastic lawn chair, which he
positioned directly in line with the strongest microwave beam. Baker
had not been told about a tenfold boost in microwave power planned that
night to handle the anticipated increase in holiday long-distance
calling traffic. Baker's body was discovered by the daytime watchman,
John Burns, who was greeted by an odor he mistook for a Christmas roast
he thought Baker must have prepared as a surprise. Burns also reported
to NMSR company officials that Baker's unfinished beers had exploded.
