As many of us oldsters recall, Jimmy Durante always closed a show with the line, "and good night, Mrs. Calabash, wherever you are." Although it was widely assumed that this referred to his late wife, no one really know who Mrs. Calabash was (he never explained). Does this give us any clues?

Here's a site which addresses this question, Boby. The link courtesy of Dr. Bill from another time when this was discussed:
