I like some of the safety warnings in John Deere equipment manuals, including this one:

which is a reminder not to drive your mower over small children.

I think that's sound advice. Similarly, you have to tell some people
not to eat nut & seed shells. Someone asked the Straight Dope about
"CAUTION: Remove shell before consuming nutmeats" on a bag of peanuts:

They [the manufacturers] tell of one character who ate an entire
eight-ounce package of sunflower seeds, shells and all, and
suffered an obstructed colon as a result. (An obstructed colon,
which can be caused by too much roughage, is basically the world's
worst case of constipation. Fecal matter backs up inside of you,
developing the consistency of a brick.) The victim, dismissing the
possibility that she may have brought this on herself, demanded
compensation from Ace, but gave up after the company pointed to the
warning that appears on all its products with shells, sunflower
seeds and peanuts included. Admittedly it looks silly, but you can
understand the problem.
