Okay this is my theory on getting a no school day..
YOU NEED TO WEAR YOUR PJ'S INSIDE OUT!!!
I works b.c it happened to me once.
Everything you wear to bed must be inside out, and the scary thing is some people don't wear anything to bed.
Well then you are screwed or wear something to bed that night.

Try it you will see what I mean.
Also if you live in a hot climate then this might not work either. But for winter climate, and your weather man said you are proably going to get snow this is who should do it..
