I usually read the labels and instructions from the products I purchase. I notice that most of them, no matter how simple or basic they are, have labels warning people not to do certain things with them. Here are a few I find funny:
Plastic wrap/packaging big enough to wrap your head in: “Warning, placing head in packaging may cause serious injury or death.”
Freshness pack in any pill bottle: “Do not eat. Can cause serious injury.”
Electric hair clippers (I just bought one) “Do not operate in the shower or bath tub. Serious injury or death may result.”
Razor blades. “Warning, sharp.” REALLY?
I know there are a million more examples because there are millions of morons running loose in our streets. Feel freee to add to this list for dumbasses!
