ISTANBUL, Turkey - First one sheep jumped to its death. Then stunned Turkish shepherds, who had left the herd to graze while they had breakfast, watched as nearly 1,500 others followed, each leaping off the same cliff, Turkish media reported. Link to article
Well, that's sad. But I'd rather deal with suicidal sheep than Monty Python killer sheep. "Now, normally a sheep is a placid, timid creature, but you've got a killer."
The untold part of the story is that these were no ordinary run of the mill sheep. They were actually a new variety of hybrid sheep. With the dramatic decline in worldwide sheep fertility and population, geneticists were experimenting with cloning the genes of the undisputed fertility champion of the mammal world into the common low fertility sheep. Unfortunately the scientists were unsuccessful in removing the suicidal gene of the donor lemmings. :wink: [Lemming fertility is so high that in the 16th and 17th centuries there was much speculation in learned circles that lemmings were in fact spontaneously generated by conditions of the air.] http://en.wikipedia.org/wiki/Lemming
