Cassandra Peterson Unbelievable Quotations

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?
