I've always found it amusing when you open a product and there is some sort of warning about not doing something extraordinarily dumb with the product.
No doubt some idiot won a rather large lawsuit (or at least filed one) blaming the manufacturer for their own profound stupidity. You shouldn't have to be warned not to stick a cattle prod into your nose, it goes without saying that you shouldn't reach under a running lawn mower. And yet, we are warned not to do these things.
The people who actually do these things have to be the ones you knew as children, who did ridiculous things under the auspices that their parents hadn't specifically told them NOT to do it. You know, like dad didn't ever say not to pour gasoline from a mason jar onto a burning fire. Have fun in the burn unit.
In all seriousness, I think a prerequisite to attempting to shift blame for your lack of intelligence onto a manufacturer should be filling out a form called "What did you think was going to happen?" In it, you have to chronicle your total lack of common sense and complete inability to foresee any natural consequence of your brain giving you the thumbs up for something patently stupid. No form, no lawsuit.
Companies are known to be negligent from time to time, but they should not have to account for the bozo who thinks it's a good idea to fashion plastic wrap into a parachute and jump from the roof of their house.
My brain is a curious thing. It bounces from place to place, from the exceedingly strange to the terribly mundane. Every once in awhile, something will pop into my head that is just completely out of nowhere. Totally random.
