I think they should do away with those warning signs, stickers, and instructions that are painfully obvious.  I think it would make the world a better place by making it impossible for certain people to do/use certain things.  Like the instructions on how to buckle one's seat beat while on a plane.  If you can't buckle your seat belt, you shouldn't be allowed on the plane.  That warning that says "Objects in mirror are closer than they appear."  If you don't know how your rearview mirror works, you shouldn't be allowed to drive.  That warning on coffee cups that says, "CAUTION!  This beverage is extremely hot."  If you don't know that coffee's hot, you shouldn't be allowed to drink. 

There was one at my former employer:  A coffee maker was right in front of a kitchen cabinet.  The coffee maker had warming plates on the top so that you could keep several pots of coffee warm at one time.  There was a sign on the cabinet that said, "Remove coffee pot before opening cabinet."  The reason that's so funny is not because it probably happened in the past, but because it probably wasn't a one time thing. #psychology
