S02 E48 Lemmings

Have you ever heard of the fabled lemming?A Lemming is a small rodent, a bit like a small mouse but more of a vole, with a short tail. Every five to seven years, they are said to instinctively recognize they have overpopulated, and a large group of them will head off in a furry little heard, and commence to stampede headlong off a cliff and into the sea, committing mass suicide for the benefit of the colony. Lemmings are cute little mammals who seem to love life in a beautiful environment. They are not melancholy balls of fluff that sit around contemplating the existential questions, who get depressed and angry about their existence,  then get all wound up and stampede into the ocean.That is a myth.How the heck did we ever come to believe this?
