A sheep loses its horns on the ground so it picks them up in his mouth to take them to a morally good doctor who is good enough to attach them back onto his head. This poor sheep lost his horns and now feels quite sad. Sheep don’t have hands, so the sheep had to pick the horns up off the ground with his mouth. An evil doctor would just murder the sheep and steal his horns, so the sheep must find a morally good doctor to reaffix them.
Since you are a morally good doctor, you decide not to murder the sheep and harvest its organs. Instead, as a practitioner of the good teachings of Zen (ぜん) Buddhism, you decided to help the sheep out. Your Zen teachings have only increased the power of your healing abilities, so you fix the sheep up in no time.
