One of my sorority sisters introduced me to my now-husband during my freshman / their sophomore year of college. I have absolutely no recollection of this - he was a friend of my sister's, nothing more.
During my junior year, he got a group of friends together (including my sister) to watch a TV program that I happened to like too... unfortunately the program conflicted with another TV program that a lot of people on my floor liked, so I was outvoted for the floor lounge TV, so I wound up joining up with this other group. I had to borrow a tape from him to catch up, so I got to see his dorm room, a really small single where he'd lofted his bed, stacked his bookcases and mini-fridge very efficiently, etc. I remember commenting on how well he'd arranged things in the limited space he had.
A few months later, after I'd gotten rid of the psycho I was dating and he got rid of the Wellesley chickie he was dating (who was just using him so she could go to senior ball

), he and I got together, and the rest is history
