I am sure this probably happened in a lot of your schools... I know it has happened 3-4 times at my old school... Sadly, the only thing I ever got was to make out with a T.A. during my grad party and I shared a few bong hits the the principle as well... this was back in '04 when I graduated though...
However I know of a few recent/pending lawsuits and I know one teacher got fired for slammin' a couple cheerleaders and they settled out of court (both girls where 18 at the time he was caught). Then a lawsuit due to a male teacher walking around ***** in the locker room and apparently asking a couple kids (like 11-13 year olds) for "****** favors". He was also the wrestling coach for like 6-8 years prior to this... //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif now he is like assistant principle or some shit...
