When I was much younger (and agile) I worked on a dairy farm milking cows. Every evening as I drove the herd to the barn, one old crippled cow always held things up. She could barely walk, and procrastinated the whole way making the job take longer. One day, getting impatient with her, I decided to try out "cow riding." When the horse pulled up even with her, I hopped off and landed on her back nicely.
When she was finished bucking and stomping me into the ground I remember thinking, "Who would have thought cows were such good fakers?"
