Back to “fun with words.” I think I kinda lightly touched on the “which words are okay” angle here (which Balder addressed marvelously back in 2007) but most of the focus is just on the kid completely misunderstanding the point of rephrasing his work.  I originally just ended with the “anal extraction” line (a term I stole from my Dad, and which I believe I mentioned at some point in the comments for another strip,) but I added the final sentence just to properly line up the dialog with the frustrated and tired look on the kid’s face.

MRS. SHOEBOX’S ASSESSMENT OF TODAY’S STRIP:  That one’s cute.
