Well, damn. No more free dental work for me. At least I can still use my drill press to clean my bellybutton.
The best one, IMO, is the one that says “shin pads cannot protect any area of the body they don’t cover.” [Homer]Not unless they’re magical shin pads![/Homer]
But I feel compelled to point out . . .
The “recycled flush water” label clearly shows water coming out of a faucet. I seriously doubt that it was meant to be stuck on a toilet. If you think of it being placed on a sink in an area where there’s a limited water supply (say, a rest stop), then it’s not stupid – in fact, it makes a lot of sense, since people tend to assume any water coming out of a faucet must be potable. Anyhoo, funny link. 
Hmmmm…can’t use the drill for dental or medical purposes. Well, shit! It would have been perfect for trepanning!
Good old MLAW. When I was still working in Cleveland, I used to work with Robert Jones from MLAW all the time, since they were a client of ours. I laughed when I saw his quote, “Despite the obvious humor in the wacky warning labels, the purpose of this contest is not to make fun of those who put obvious warnings on products.” He never struck me as a guy with much sense of humor! He was nice and easy to work with, though.
Water in body cavities… mmmm…
Should I look at these or will I not be able to get to sleep for laughing tonight?
It still could be…just prop a big box over it with a stick, and when someone who really likes drills goes after it, pull out the stick.
(Trepanning also refers to entrapping or luring someone.)
Power drill? How about a warning on an Ice Skate:
“Blade of ice skate is not intended as a dental tool”
My favorite warning label was on a dry-cleaner’s bag, which I cut out and pinned to my bulletin board: TO AVOID DANGER OF SUFFOCATION, KEEP AWAY FROM BABIES AND SMALL CHILDREN.
Those are words I try to live my life by.
