(1) who specifically, or at least when specifically, did originate the phrase?
{Example answer - "that was one of Shakespeare's!"}
(2) why?
(3) when first did someone screw up and use "..dishwater"? why? who?
Thank you.
(PS note that in print, apparently "...dishwater" become more popular from about the 1970s. I am interested in the above three questions, if anyone has any info on those three specific questions, thank you in advance.)
BTW I appreciate this question may be "easily answered by some reference book", if so, please (A) tell me the book and (B) close the question. (I'm afraid I couldn't find anything.)
