You see, Jo is a bit of a martyr. Not because she beats her chest and talks about her difficult days, but because she grew up in a small town in Kansas and married a man with a Kosher Dairy kitchen.
For those of you unfamiliar with the rules of Kashrut, that means there are no meat products or byproducts in the house. None. Except fish, cuz ya know, fish isn’t meat (doesn’t matter a bit though cuz no one wants to eat it unless they’re dying). Yes, dear goyim, I understand that fish has flesh and a nervous system, that it isn’t a plant, but fish isn’t meat. Please don’t interrupt the laws of Kashrut with logic, the rabbis have bickered about this for many millennium.
