Not quite the question BUT:
My friend once found an old dud (he thought) mortar shell once while out with the Scouts. He took it home and placed it on his shelf, where it remained innocently for several years. Until his mother insisted he remove it that is. Being a sensible and civic minded young lad he trotted along to the police station, clutching his unexploded bomb under his arm. Upon arrival he placed it on the desk, explained what it was and watched as the entire Angel, Islington police station was summarily evacuated, and the Bomb Squad called in to defuse it. In the end, it did turn out to be a dud - and no charges were pressed - but the incident got written up in the Islington Gazette (and a front page no less) under the headline "Teenager Wanders In Off Street With Unexploded Bomb." Which he was rather chuffed by. And I have a copy of the paper, if any proof is required!
