Have you ever had one of those WTF moments in school?

For me, it was during high school in spanish class. Our regular teacher was out sick, so a substitute teacher was teaching the class that day. The sub didn't really care about what we did in class so I decided to get some sleep. Probably a bad idea but there was nothing else to do. So I slept through the class a little longer then intended. When I awoken, I looked around the class thinking to myself, "Who the fuck are you people?!". It turned out, I slept passed the class period and no one seemed to care to wake me up to go to my next class. NO ONE! So I just got up feeling kind of awkward and just left to lunch since I was already counted absent to my next class.
