Almost up to Possible

I listened with interest to your December 15 podcase on "Possible," and have something to share.
During her last days, while receiving a spongebath in the hospital, my elderly mother said, "Wash up as far as Possible; wash down as far as Possible; then wash Possible."
I had never heard her say it in all my years of growing up, but it surely fit the situation! She said that her mother used to say it. They were both raised in Michigan.
