I was just curious, though, where the joke "Is the Pope Catholic?" originated, and I discovered in originated in 1967, the same year the first Novus Disordo "Mass" was being celebrated in the Sistine Chapel.
So originally it was probably a real question, not what it has turned into today.
In the U.S.A., the older Cradle-Catholics who were discombobulated by Vatican II were nevertheless the product of generations of obedient laity, confident that their clergy wouldn't lead them astray. The younger Cradle-Catholics typically welcomed
Novus Ordo "guitar Masses" &c. as just another aspect of the excitement of the social change of the '60s.
The
subject joke did originally express the more-perceptive laity's exasperation, under the cover of sarcasm. So its sense really was
not much different from
what it is today.
There was a
much earlier joke, which had floated around for decades: "
Is the pope Italian?"  It satirized the papacy's centuries-old status as a
de facto hierarchical entitlement for Italy & Italians. Readers who were born after Vatican II and the
Novus Ordo revolution have grown up without any sense of how
alien a concept it was for the Sacred Conclave to
elect a nonItalian as pope. Yet now the
Novus Ordo has 3 in a row: Polish, German, and Argentinan. It's too soon to've forgotten that iconoclastic forecasts swirling around the latter conclave favored election of a nonhyphenated African.
