Granted. The prof. shows up, but forgets which class he's supposed to teach, and starts lecturing on grad-level petrochemical engineering. The students get totally confused, can't convince the prof. there's something wrong. Eventually, this prof. gets fired for incompetence, and the school can't find another, so you can't finish the class, and can't finish your degree.

Meanwhile, the prof. was out last week because he had extreme drug-resistant TB, and by showing up this week, he infects all the students in class, causing an epidemic that makes swine flu look like a mild cold.

I wish weather forecasters could be 99 percent accurate.
