“"Ladies and gentlemen," the professor started, "today I want to talk about fat ..."
I heard the rattle of paper. Hundreds of copybooks were opened and pens were ready to write.
"Last winter you had your first course in the dissecting room," the professor continued. "You worked on corpses, studied the skin, muscles, and organs. But one thing you missed out on, and for this I want you to accept my apologies ..."
For a fraction of a second he paused.
"You missed out on fat!" he resumed. "We had no way of letting you dissect fatty tissue. Sorry, but those corpses were poor material -- they were prisoners who had either perished or were executed in camps."
Hundreds of students were listening, but their faces stayed blank and their hands did not move. Nothing had been said worth putting on paper.
The professor stepped over to the blackboard and took up the chalk. The audience came to life, and brains and pens went to work.”
