Navy man shoots self accidentally

11. Not the dumbest thing I've ever heard of.

Actor Jon-Erik Hexum did something even dumber with a firearm. From Wikipedia:

On October 12, 1984, the cast and crew of Cover Up were filming the seventh episode of the series, "Golden Opportunity," on Stage 17 of the 20th Century Fox lot. One of the scenes filmed that day called for Hexum's character to load blanks into a .44 Magnum handgun. When the scene did not play as the director wanted it to play in the master shot, there was a delay in filming. Hexum became restless and impatient during the delay and began playing around to lighten the mood. Apparently, he had unloaded all but one (blank) round, spun it, and in what would appear to be a game of Russian roulette, at 5:15 p.m., he put the revolver to his right temple and pulled the trigger.

Hexum was apparently unaware that his actions were dangerous. Blanks use paper or plastic wadding to seal gun powder into the cartridge, and this wadding is propelled from the barrel of the gun with enough force to cause severe injury or death if the weapon is fired within a few inches of the body, especially if pointed at a particularly vulnerable spot, such as the temple or the eye. Although the paper wadding in the blank that Hexum discharged did not penetrate his skull, the wad struck him in the temple with enough blunt force trauma to shatter a quarter-sized piece of his skull and propel the pieces into his brain, causing massive hemorrhaging.

He knew the gun was loaded, but thought blanks were harmless.
