There was a version I head as a little kid (again about 50 years ago) that included a lady named Keller, the (pot) didn''t work, but they didn't tell her, she flushed it and went clear to the celler, and nobody knew she was there. There was also a verse about a lady whose name rhymed with sooner.   . The ( )th old lady (something 'ooner) went to the bathroom and wisedh she'd gone sooner. The verse about Mrs. Draper went that she went in and found no paper, not even a corn cob could she find, and nobody knew she was there.
