I just read from my local newspaper's web news that some Finnish dude had found a WWII AT grenade in a forest and following the most brilliant logic ever he brought it to his garage and proceeded to drill it. But God favours the fools and thus he didn't die in the ensuing explosion.

The most strange thing about the case is that no alcohol was involved, so he was sober when he decided it's a good idea to drill an old explosive.
