"Whoever you are—I have always depended on the kindness of strangers." Awesome. It's a Tennessee Williams potpourri. First we get Mary Worth thinking she's Blanche Dubois, and then an oblique reference to Laura Wingfield's blue roses - although, let's give credit where credit is due... the blue roses were purely the work of coloring artist, 5th grader Beatrice Chestnut.
I want to give additional praise to the Cosmic Bubbles blog that has run a couple of recent Mary Worth cartoons through the anagram machine: Here and here. Hilarious!
