Check out this cartoon by Neil Wagner at Science Friday. What makes it extra worthwhile is the exposition below his cartoon where he explains the concept of positive feedback and links to a bunch of useful webpages (including this one). For the record, I once had almost this identical conversation with Wendy about positive feedbacks (Wendy was the polar bear).
