10) People actually do these things. We all break the rules sometimes and it's just a short step from operating heavy machinery after taking cough medicine to ironing your clothes while you're wearing them.
9) Because they care. The makers of these products genuinely care about each and every one of us and they don't want to see us get hurt. Or, more cynically...
8) To sell products. Nothing raises product awareness like a mention in "100 Stupidest Product Warnings". Or, for that matter, on Worth1000.
7) They want to attract all those daredevils who wouldn't normally buy their product. All those ideas of dangerous things to do with it...how could they resist?
6) It's reverse psychology. Nothing makes you want to do something more than being told not to. All these companies are in league with the local hospitals. It's a conspiracy. It's true, I tell ya, true...
5) They want to scare you. They love watching the look on your face as you contemplate just how that screwdriver you bought could be used internally.
4) For fun. It's not the most glamorous job being a safety label writer - can you blame them for wanting to exercise a bit of creative license? They watch old horror films every night to get ideas of what gruesome things each product could be used for.
3) They like to challenge us. Give our brains a bit of a workout. They print "Do not open for at least one hour after purchase to allow contents to settle"...and they print it on the inside of the box. Then they sit back and watch us puzzle it out.
2) It's all been lost in translation. It made perfect sense in the original Korean. Yes, that's it...blame the foreigners, that's what I say.
1) One word: lawsuits. It costs a lot less to print "This Superman suit does not enable the wearer to fly" than it does to compensate hoards of crying mothers whose children have leaped from their eighth-storey window.
