I'm not sure if he's still there, but I remember a guy who used to speed walk around U of C (early 2000's) always dressed the same - grey sweat pants & black tee shirt - with a HUGE duffle bag always on his shoulder. He was quite tall and had a bald head and he always reminded me of that white "Micheal Jackson" that Homer meets in the mental institute ("happy birthday lisa...."). I would also see him from time to time randomly around town always dressed the same and often reading a book while speed walking.
There was supposedly a legend about him, that he was badly hit by a U of C maintenance vehicle and thus granted lifelong free tuition in exchange for no publicity/lawsuit.
