Dead cow lecture

First-year students at the Purdue 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 that

you not be disgusted by anything involving the animal's body." For an

example, the professor pulled back the sheet, stuck his finger in the butt

of the cow, withdrew it, and stuck his finger in his mouth. "Go ahead and do

the same thing," he told his students.

The students freaked out, hesitated for several minutes, but eventually took

turns sticking a finger in the butt of the dead cow and sucking on it.

When everyone finished, the Professor looked a 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.
