Dead Cows are Funny!

VET CLASS
First-year students at Texas A&M Vet School were receiving 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 vet 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 dead cow, withdrew it and stuck it 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 anal opening of the dead cow and sucking on
It. When everyone finished, the Professor looked at them and told them "The
second most important quality is observation. I stuck in my middle finger
and sucked on my index finger. Now learn to pay attention !
