On the first day of class, a professor told his veterinary students that a good doctor needs two skills: never being disgusted by animals—and paying close attention. To prove the first point, he stuck his finger into a cow’s rear… then put it in his mouth, telling the students to do the same.
Hesitant but obedient, the students followed, gagging through the ordeal. When they were done, the professor smiled and revealed the second lesson: observation. He had used one finger on the cow—and a different one in his mouth. The real test, he explained, wasn’t bravery… it was attention.
