Lemmings with suicide vests. It's kind of an insult to lemmings to call them lemmings, so they'd have to be more than just a lemming, because jumping to your death is not enough.
I'm not a lemming about to run off the end of a cliff.
I'm driving down the freeway the other day, on my way to Knott's Scary Farm probably, and I hear this report on NPR that the whole lemmings thing was faked in the 1950s. They were shooting a wildlife documentary in the '50s, they found a group of lemmings, and the crew chased them all off a cliff. No lemming has ever jumped off a cliff, purposefully, ever. Isn't that unbelievable?
