I remember one day a rumour spread like wildfire that someone in our year had been stabbed during Tech. Turns out they'd had an argument and one guy threw a compass (or something sharp at least) at him at speed and it pierced him, I knew them well and I think they were quite good friends until that. The police were called and everything
The BEST story I have though is from first year of uni. A video started doing the rounds (mainly through YikYak </3) of this guy wanking and shoving a dildo up his ass in the middle of the quiet floor of the library. It must've been during the night cause somehow no one was around, and he uploaded it to tumblr under the name 'youngcumlover69'

which subsequently became a local meme
The security started doing hourly patrols around the building after that
