Did you know that without their antennae, pillbugs will not roll up? Just something interesting I found out in a misspent amoral youth. And to balance out karma, I also farmed and fed them, so don't hate me.
Some other interesting facts: they're actually crustaceans like lobsters which is probably why they like moist surroundings, and if you eat them alive, they'll climb up your esophagus until you wash them down. That last part is not personal knowledge.
