I enjoyed it greatly—and I’m Catholic (but I teach Scripture and have a great admiration for rabbinic exegesis, thought I don’t know it nearly as well as I would like). There are similar strands of funny legalism in some schools of Catholic theology. I have a great work of moral theology (four volumes) by a Jesuit from the late 1930’s that has huge lacunae of many sorts, but is worth the purchase price for the paragraphs explaining where and why beavers are fish.
LOL. Some of the early Spanish explorers of the Gulf Coast developed a fondness for Manatee for similar reasons. At least one journal entry refers to it as the fish that tastes like beef.
Actually, the modern Jewish view of things religious couldn't exist without such rules because righteousness is based on how well one obeys a large list of commandments whose ramifications range from the sublime to the ridiculous. Correct categorizations are absolutely essential to any kind of assurance that one is obeying correctly.
That said, the sort of questions that comprised the punch line in the original article would be like asking whether it's okay for your Hanukkah latkes to be fried in corn oil vs. olive oil, butter, or chicken fat, and does it have to be on a gas stove or could it be electric?
