Chandler Bing shouldn’t have made sense. The character was a mass of contradictions that didn’t add up, at least on paper, in 1994, to a recognizable “type.” Here was an objectively good-looking man — funny too, of course, as well as sarcastic, silly, smart — saddled with a wildly disproportionate sense of his own inadequacy. But Matthew Perry, who died Saturday at 54, played the jokester on “Friends” as a clever clown in torment.
