Read Before Lunch

First-year students at Texas Vet School were attending their first anatomy class, with a real dead cow. They all gathered around the surgery table with the body covered with a white sheet.
The professor started the class by telling them In Veterinary Medicine,it is necessary to have two important qualities as a doctor: the first is thatyou not be disgusted by anything involving the animal body.??
As an example,the professor pulled back the sheet, stuck his finger in the butt of the dead cow, withdrew it and stuck his finger in his mouth. ?Go ahead and do the samething,? he told his students.
The students freaked out, hesitated for several minutes, but eventuallytook 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 secondmost important quality is observation.? I stuck my middle finger in the buttand sucked on my index finger.? Now learn to pay attention.
Life's tough.
It's even tougher if you're stupid
