SHEEP ARE TAKING OVER THE WORLD!!

Well, I know that the topic title is a bit of a wierd one, but there is a reason!! Basically I was up in Northumberland with my parents a few months back and a farmer told me that he couldn't do any work because he got his leg broken by a charging sheep (he should of taken away it's credit card really <--bad joke!!), so, naturally, I thought "sheep are secretly taking over the world!!". So, this wierd inter-planetary story started to form, which is apparently very funny....anyone need any ideas for a story an I'm sure I could think of something....my imagination works over-time all the time (or so I've been told!!).
