a clever sheep

I heard this story in the pub the other day about a really clever sheep. His flock was confined to their field by one of those cattle grid things that they couldn't walk over. Well, this sheep figured out that he could cross the grid by rolling over it. And once all the other sheep saw him they copied his idea. This got us thinking, how many people have truly original ideas in their lives? Are most of us just copying things that have already been done by other people? I reckon I don't want to be a follower sheep anymore - I want to be a sheep that rolls. Um ... now I just have to come up with an original idea ... any thoughts?
