Howard Price asked:
John, where did this happen?

It happened on Usenet. I can't recall at this remove whether it was actually in the then-regular postings of Cho's newsletters to rac* groups by Allan Gross, or if people who'd received it in email were discussing it. But I certainly read there, before the Journal issue came out, that Cho was entreating people to beg their papers to kick Schulz out and make room for a crazy monkey who mocks DA MAN.
