Actually, I'm not at all sure how "weird" this is -- it's just one of those cultural differences. Anyway, when one reads a lot of cookbooks and food history, a theme one quickly detects is that foods of necessity in one era eventually become foods of delicacy for the next. Case in point: In Cambodia, spiders are a gastronomic delight.
As I note, this is really more of a cultural difference; I'm sure there's some staple of American diet that the spider-munching Cambodians would find nauseating. But it was a slow week for weirdness online, so that's what I'm going with. Bon appetit!
