First-year vet students were attending their first anatomy class, with a dead cow.
The professor started the class by telling them, “In Veterinary Medicine requires two important qualities in its practitioners: The first
is that you not be disgusted by anything involving the animal body.”
She then stuck his finger in the butt of the dead cow, withdrew it and stuck his finger in his mouth.
“Go ahead and do the same thing,” she told her students.
They were understandably hesitant but eventually took turns sticking a finger in the butt of the dead cow and sucking on it.
When everyone finished, the professor looked at them and said, “The second most important quality is observation.
“I stuck in my middle finger and sucked on my index finger. Now learn to pay attention. Life’s tough, but it’s even tougher if you don’t use your eyes and your brain.”
