Love your username if only because it reminded me of that grad algo class and Prof, some hilariously awkward dude who invented some quantum alkhwarizmi, started ... "There was this guy ... Named Al Khwarizmi. Al..Khwarizmi Alkhwarizmi Hehe. Get it?" he also once started the class with a lecture for a different class and everyone was confused till the TA intervened. convinced it was all precalculated comedy of errors.
