Adultproof is what happens when a manufacturer goes overboard in creating childproof packaging.

Right now, I'm trying to open a container of vitamin pills. I've removed the plastic wrapping around the top, and now I need to temporarily remove the screw-on top in order to remove the piece of cardboard that is covering the actual opening. I cannot open this top. The snap-on lid that will serve as the actual "opening" once I've got the cardboard out has come off, and the screw-on lid is festooned with bite marks. To no avail. I may have to take a knife and just cut out the cardboard.
