This reminds me of a sentence I once heard as an example of
inscrutability. Written without punctuation, it goes:
Jack when Joe had had had had had had had had had had
the teachers approval.
Properly punctuated, it says:
Jack, when Joe had had "had", had had "had had"; "had had" had
the teacher's approval.
The context is supposed to be a comparison of the words two students
used in their essays and how their teacher reacted. It actually
makes sense when read carefully.
