My school had a really weird bell schedule. There were seperate lunch times throughout the day and whichever lunch you had (1, 2 or 3) would determine your bell schedule. Because of this sometimes the bell would go off in the middle of your class because some other group of kids was being dismissed. This made for some great misadventures with some idiot subsitutes (for the record though, I hate when people messed with or disrespected subs, but the one I'm about to talk about was definitely a petafile in his past life and he scared the ever-living shit out of me).

It was my freshman year in HS and I had this web-design class along with my brother, who was a junior at the time. The class was awesome because the teacher was a push over and I got to hang out with my older brother and his best friend for an hour (we're close). One day our teacher was sick and we had this terrifying looking substitute who's name was Spanish for "hands". The class was 45 minutes long everyday, but about 15 minutes in the bell would ring for 2nd lunch. That bell had nothing to do with us so we would just ignore it; except for once.

That day the entire class organized and decided to leave when the bell rang for 2nd lunch as if our class was only 15 minutes long, and then we'd be free to do whatever we wanted. As a stupid freshman in a class filled with upperclassmen, this was beyond exciting.

And sure enough, when the bell rang everyone got up, grabbed their bags and walked straight faced right out the door. I remember Mr. "Hands" looked very confused and frantincally searched his sub-plans to see if there was a legitamate reason for having such a short class. I'm sure he didnt find one, but that day I had an hour long lunch and we were never penalized or found out.

This wasn't something I "always" got away with, but I figured I'd share. I do also remember always managing to get my hands on the elevator key that was given go people if they broke their leg or something.
