Talking about finding explosives. This apparently happened yesterday in my hometown (Venlo). A man walking his dog picked up a HE grenade after his dog peed on it and the item in question started making a hissing noice. He immediately called 911 and got the advise hold on to the grenade and not to move or place it back on the ground. Since it took the bomb disposal unit several hours to arrive on the scene the man decided to lay down on the ground while still holding on to the grenade. Meanwhile the man started to show signs of hypothermia. Luckily it transpired that the WW2 grenade didn't contain any explosive material.
Well, if it was april first I would not have believed one word of this story but it actually seems to have happened.
