I asked John Lamping about what the "Testing on the Toilet" people tell
the Google employees. Below is his response.

I haven't heard back from the Testing on the Toilet people to know if
it is OK to distribute this episode outside.  But I did a search, and
found earlier episodes that were published publicly and that mention
the Law of Demeter.  This one, for example:

This search finds all dozen of them:
