Little suction-cup soap holders you can slap on the face of the offending instruments so they can stop trying to deceive and kill you.
I found a couple of 'em in the glove box of my "new" Bo- nice!
I do have a few of those and at the time I know I had a couple of them in my flight back. The trouble was that I was way too busy to try and get them out. I have never heard them called soap dishes before.
