One of our quietest teachers ever made a one hour long lecture about how we weren't studying enough, and how we didn't even diserve to be there, shouting as loud as hell. Until suddenly stopped and let out the classic "April Fools"
Also, the janitor shut off all the lights in school. My class ends at 20
omething, and my class's windows don't have any light poles near, so it actually meant "no lights".
After "waisting" 3 hours in an elipsis problem (I'd be happy if any of you could solve it later, btw =P), he just "figured out" he had commited a mistake right in the beggining (which would've meant 6 sheets of paper being thrown out, and having to draw those ** elipsis again). Hated this one, glad I didn't throw it out
After being on school since 8 a.m. (tests were transfered from saturday to today because of the holiday), the cafeteria people told us there was no food available.
and some more others, all school related =( Hate when have to be there for the whole day.
