The *Mad *satire (“Room 222ZZZZZ…”) marveled that within the perfectly integrated student body, there were no interracial couples (the illustration showed white couples, black couples and an Eskimo couple).
This *really *reaching into the mists of obscurity…
Not long after “Room 222ZZZZ…”, Mad once included an insert that contained capsule-description satires of TV shows. It used photographs instead of the artwork *Mad *was known for. I’m almost certain it was done by someone other than the"usual gang of idiots" - it was edgier, more adult humor.
One of the satires was “Room 347”. A photo showed the principal’s office (with his name spelled, “Mr. Coughman”). The school was named, “Totally Integrated High School”. Spell the acronym backwards…
Unrelated to the OP:
Another satire in this insert described “The Even Newer Dick Van Dyke Show”, a comment on “The New Dick Van Dyke Show” which was less successful than “The Dick Van Dyke Show”. The capsule described how this would be the first Dick Van Dyke show that would be filmed without Dick Van Dyke: the plot would claim that the star was snowed in at a ski cabin somewhere for the first half of the season, hopefully until the series was renewed for a second season.
Mad were the masters of the cynical behind-the-curtain look at the motivations of big institutions like TV networks. But that insert seemed to take things further.
