Here is where the Diapers/Beer NOT LEGEND came from:

Subject: Origin of "diapers and beer"
For my invited talk at ICML in 1998, I tracked the beer and diapers
example further. Check out slide 21 in
http://robotics.stanford.edu/~ronnyk/chasm.pdf
Basically, I found the person in Blischok's group who ran the queries.
K. Heath ran self joins in SQL (1990), trying to find two itemsets
that have baby items, which are particularly profitable. She found
this beer and diapers pattern in their data of 50 stores over a day
period.
When I talked to her, she mentioned that she didn't think the pattern
was significant, but it was interesting.
