While cleaning out files came across many things from  teaching school. One of the things was an announcement I had written for the principal to read over the PA system.
The other special area teachers had bet me that I couldn't get our principal to read a really stupid  announcement. ( He didn't have much of a sense of humor when it came to looking silly) Well, game on!.....
They didn't think it could be done but I had great confidence that it could be pulled off.
 I usually had an announcement to be read once a week or so anyway when I needed kids to bring in specific items ,so an announcement from me was nothing new.
I created a double-sided announcement. The front said "Newspapers are needed in the art room. Anyone-"
(Then it had to be turned over to read the rest.) which said- "have their hair dyed green should report to the art room at lunch time!"
Well, all of us hid in the gym during morning announcements, waiting with baited breath. Sure enough he began reading my innocuous announcement, then got to the back of it. There was the longest pregnant pause in the history of man. He didn't know what to do but knew he had been had. So he finally read it as written as fast as he possibly could. We were all laughing hysterically; you could probably hear us throughout the building.  He (the principal) ended up not speaking to me for a week. But..I won the bet and he finally forgave me.
