A couple of years back, while attending college, I can remember one interesting class.  You see, it was an English class where the first thing the professor said in front of the class was this:

"I am sad to report that all of your research papers have been stolen."

What?

We’ll as it turns out, someone broke into the professor’s office, took the term papers and ran off into the night.

So the professor told us we had to resubmit a termpaper by the following week.  Unfortunately for me, I deleted it off my computer, so I had to rewrite the essay from scratch.

I learned a valuable lesson that day: keep copies of all your papers until the term is over just in case something like this happen.  Strangely enough, a similar thing would happen two years later - at least I was prepared that time.
