The really charming thing about ASAP Science's series of whiteboard explainers is the cute, simplistic cartoon images that accompany them. Perhaps it's Halloween in the air, but they've taken a turn toward the macabre with their latest video. It's all about parasites, and their cute drawings of worms, mites and lice that live in our hair and under our skin are accompanied by actual images of the tiny monsters.
So, be warned. Be warned, also, that the video includes the phrase: "Your butthole becomes a nest." Oh, and you might never eat sushi again.
