The Spherical Cow

A dairy farmer is struggling because his cows are not producing milk. He reaches out to the local university for help and they say, don't worry. We're going to send out a multi-disciplinarian team. A month later he's still not getting dairy from his cows. The theoretical physicists responded with,Don't worry we figured out the problem. We just need to start with a spherical cow in a vacuum. Not particularly at the end of the day, but I have a story.
