First-year students at Texas A&M's VetSchool 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 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."

 "Life's tough, it's even tougher if you're stupid."
