drool-proof paper
     
         Documentation that has been obsessively {dumbed
        down}, to the point where only a {cretin} could bear to read
        it, is said to have succumbed to the "drool-proof paper
        syndrome" or to have been "written on drool-proof paper".  For
        example, this is an actual quote from {Apple Computer}'s
        LaserWriter manual: "Do not expose your LaserWriter to open
        fire or flame."
