I am very sad to learn of the death of Michael K. Williams, whose character Omar Little was one of my favorites on The Wire (and I am not alone in that regard). I especially loved his unusual combination of menace, Zen and cheerful whistling, as well as his fierce independence. But I also really enjoyed his performance on Community as Marshall Kane, a biology professor who earned his PhD while in prison. He was hilariously solemn, something which I, as an educator, aspire to myself. He will be sorely missed.
