in thread Old sorting paper holds the key to unlocking the secrets of the Schwartzian Transform

The original I heard was "John where Jim had had had had had had had."

Then, there was the proposal that a second John and Jim had been given this sentence to punctuate, and the second John had given up in disgust:

John, where Jim had had, "John, where Jim had had 'had', had had 'had had'", had had "John where Jim had had had had had had had".
It's probably time to let sleeping hads lie at this point.
