I lived in the dorms for 3 years in college and have some pretty crazy stories. Oddly enough they all involve drinking! Let's see..
Okay, I had this friend that we'll call 'A'. A group of us got pretty hammered one night and eventually everyone trickled out of the quad back to their respective rooms. Some lived on different floors of this 3 story dormitory. My room was on the 3rd floor and the other guys had rooms on the 1st floor. So, the next morning I went to check in on A because he was pretty drunk the night before. He wasn't in his room and I just assumed he woke up early for some reason.
Later that morning at around 11 or 12 some random guy from the 2nd floor who I didn't know came up and asked me if I'd come to his room to see if I knew who a certain person was. I walked in and A was asleep on the bed and his face was covered in blood. Apparently he fell down the stairs from the 3rd to 2nd floor, thought he was on the 1st floor, and walked into this guy's room (the one directly above his own) and went to sleep while bleeding all over the bed.
I guess the guy didn't care because it was his roomy's bed and he was gone for the weekend.
