Freshman year, my schedule was an early morning (8AM) class every day, and then a long block of free time until the afternoon. I would come back to my dorm in between and shower and work. One of my roommates once remarked that he had never seen me do homework. This became a running joke, every time he was in the room I would be reading wikipedia or metafilter or whatever it is that all my time goes to.

One day he caught me doing homework. He laughed, and I, embarrassed, put away my textbook and instead wasted time.
