My loving teacher and the principal played a prank on the whole class. So, she had the intercom on a OD NOT DISTURB option, which is a different name for a power off button. Because of this, she makes up a BS story about flood drills. This would make sense some places, but loving eastern Kansas? We all fell for it, however, and practiced the BS flood drill...where we stand up on our chairs and stare at the door. Then, my teacher says the principal has to document it. The principal came down, we all did the drill, and she took detailed pictures of us all standing on our old blue chairs.
Then she and the teacher say it was an April Fools joke and there is no such thing as a flood drill.
