As Jeff Foxworthy once stated: "The only reason for warning labels is because SOMEBODY TRIED THIS!"
The best label I've seen was on a penlight I had purchased several years ago. It was the warranty label on the back, and it went thru half the space telling that this light was good down to 500 feet if the O-ring was intact, it was explosion proof, water proof, shatter proof, etc., etc.
That if such and such failed, take it wherever to have it repaired or replaced, etc., etc.
The last line of the warranty read:
WARRANTY VOID IN INSTANCES OF SHARK BITE, BEAR ATTACK,
AND CHILDREN UNDER 5!
