The whole “lemmings jump off a cliff in mass-suicide” thing is a stale joke, actually. It has been debunked a long time ago, which is why I groan each time this type of joke comes up. It all stems back to a “documentary” filmmaker for Disney threw a bunch of lemmings off a cliff, and claimed that this was the real migration pattern of lemmings. And for that, he won a bunch of awards, and started a terrible myth that influenced pop culture ever since.
