First-year students at Minnesota's Vet school were receiving
their first anatomy class, with a 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 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
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.
