Weekend School

Class 208 is one of the worst classes in Summerset middle school. From disrupting the class constantly to setting textbooks on fire, no teacher would ever want to be in charge of them.
After being told that a severe thunderstorm was occurring, Summerset middle school would have to wait it out, meaning that the poor teacher in charge of class 208 would have to wait it out with them.
Then, the teacher leaves them during the wait and class 208 is teacher less with no one telling them when to leave.
What kind of misadventures will the worst class in Summerset middle school would get into this time?
