Yep, I took care of sheep as part of my workstudy job while at Hampshire College. Anyone who has ever cared to ask me knows that I think sheep are just about the dumbest critters on earth. Now sheepdogs are the best. We had a border collie on the farm who couldn't be beat. Went by the name of Flea. Mind you, she could single handedly round up a small herd and bring them to just about anywhere we might want.... if she was so inclined.
This video exemplifies that AWESOME power of a well trained border collie and their shepherds. Mind blowing really!
