[a three-panel comic by Tom Gauld for New Scientist. The top border of the comic shows a two-dimensional, side view pattern of different cars lined up in traffic. The first panel panel shows two people talking. Person A is holding a book and saying, "It's hard to get excited about these new electric vehicles when I've seen much more ambitious possibilities in fiction." Person B is replying, "Sci-fi fan, huh?". In the second panel, Person A is looking at their book and going, "uhhh...yeah. Sci-fi." The third and final panel reveals that Person A is reading a book from the Busytown series, and it depicts a mouse driving a pickle-shaped car, a worm driving an apple-shaped car, and a pig driving a hotdog-shaped car.]
I was wondering if indirect cannibalism (human eating pig that ate human) would be dangerous... then I realized indirect cannibalism is always because we all return to the earth as we are fed by it.
That kind of thing is how prion diseases take off, iirc
