You've all seen the eye-roll inducing warnings on things, warnings that should be obvious. "Don't use the blow dryer in the shower?" Why would I WANT to? Isn't that kind of missing the point of blow dryer? "Warning: [costume] cape does not enable wearer to fly." Could be a really sad story behind that. Or a really stupid one.
The conventional wisdom is, a manufacturer was found liable in a big lawsuit for NOT providing a warning, so the warning label grew another inch for the next print run.
Well, I saw one today that I hope... I HOPE... is a tongue-in-cheek poke at those.
