Well, here's the dumbest thing I've ever done:

I was going to cook steaks on the grill one evening, so I went outside to check the charcoal supply. As I casually reached into the bag (without looking), I became aware of an intense burning sensation - which I discovered was due to the dozen or so hornets stinging my hand. It turns out that there was a nest. I was pretty fired up after this, so I rationally decided I would grab my air rifle and blast the hell out of the charcoal bag and teach the little bastards a lesson. Unbeknownst to me, there was a full can of silver spray paint behind the bag, which, once punctured, spun around on the deck surface and sent silver paint everywhere. So, in addition to being in agony from the bee stings, I was able to look forward to cleaning the deck off with paint thinner!
