Some actual product warning labels:

On a New Zealand insect spray -
THIS PRODUCT NOT TESTED ON ANIMALS.

In a US guide to setting up a new computer -
TO AVOID CONDENSATION FORMING, ALLOW THE BOXES TO WARM
UP TO ROOM TEMPERATURE BEFORE OPENING.
(Make sense...except these instructions we're IN THE BOX!)

In some countries (like W. Virginia:), on the bottom of Coke bottles -
OPEN OTHER END.

On a Sears hairdryer -
DO NOT USE WHILE SLEEPING.
( Now THAT I'd like to see! )

On a bag of Fritos -
YOU COULD BE A WINNER! NO PURCHASE NECESSARY. DETAILS INSIDE.
(The shoplifter special!)

On a bar of Dial soap -

(And that would be how?)

On Tesco's Tiramisu dessert (printed on BOTTOM of the box)
* DO NOT TURN UPSIDE DOWN.
(oops...Too late! You lose!)

(Are you sure? Let's experiment.)

On a Korean kitchen knife -
WARNING KEEP OUT OF CHILDREN.
(Dammit! Who are they to tell me what to do with my kids?)

On a string of Chinese-made Christmas lights -

(As opposed to what...use in outer space?)

On an American Airlines packet of nuts -
INSTRUCTIONS - OPEN PACKET, EAT NUTS.
(I'm sure glad they cleared that up.)

On a Swedish chainsaw -
DO NOT ATTEMPT TO STOP CHAIN WITH YOUR HANDS OR GENITALS.
(What kind of consumer phone-call led to this warning?)

On a child's superman costume -
WEARING OF THIS GARMENT DOES NOT ENABLE YOU TO FLY.
That's right, destroy a universal childhood fantasy!)
