I actually had Chazelle for freshman CS, many years ago. I think his style is targeted for the freshman CS kind of audience, people who aren't already into the field, and thus need some of the cuteness. His lectures were a lot of fun, by the way, and at the end of the semester, one of us put together "The Chazelle Show", basically clips of all his funniest moments.
