Cut the processing time in half while doubling the load! The average cow, pre-jamboree, spends one hour in the hospital, including time waiting for a slot in the OR. Then you give the surgeon a power saw that allows him to complete the job in half the time, but he also gets twice as many cows to work on. Most people's intuition would tell them the cows would still spend an hour in the hospital (the doubling in work rate canceled by the doubling in work amount), but actually now it takes half an hour -- regardless of how swamped the surgeon was initially.
