The Vice President is being criticized for attending the Auschwitz memorial ceremony in a ski parka and knit cap instead of a suit. Perhaps he has been overeating at the inauguration parties and his suits don't fit (not like Johnny Carson's, anyway).
As a less-than-well man, he should remember what Orson Welles said: "My doctor told me to stop having intimate dinners for four. Unless there are three other people."
Bottom line, ski parka = tres tacky. As Evelyn Waugh said, "I can abide formality or intimacy, but I detest informality."
