Via the Internet world is a list of actual label instructions on products. This particular poster comments on 15 products total; I've included 8 for your enjoyment. Visit here to read them all. My favorite is the Superman one. :)
1) On a Sears hairdryer: Do not use while sleeping.
(and that's the only time I have to work on my hair.)
2) On a bar of Dial soap: "Directions: Use like regular soap."
(and that would be how???....)
3) On some Swanson frozen dinners: "Serving suggestion: Defrost."
(but, it's "just" a suggestion.)
4) On packaging for a Rowenta iron: "Do not iron clothes on body."
(but wouldn't this save me more time?)
5) On Boot's Children Cough Medicine: "Do not drive a car or operate machinery after taking this medication."
(We could do a lot to reduce the rate of construction accidents if we could just get
those 5-year-olds with head-colds off those forklifts.)
6) On most brands of Christmas lights: "For indoor or outdoor use only."
(as opposed to... what?)
7) On an American Airlines packet of nuts: "Instructions: Open packet, eat nuts."
(Step 3: maybe, uh... fly Delta?)
8) On a child's superman costume: "Wearing of this garment does not enable you to fly."
(I don't blame the company. I blame the parents for this one.)
