Bob Newhart’s “Retirement Party” routine is about a 65 year-old guy who’s hated his job for decades, was able to stand it only by medicating himself with martini lunches, feels nothing but disgust and bitterness about what he’s made of his life, despises his co-workers and is more or less living in a pit of despair. A reflection, in short, of American middle-class life in the late ’50s under President Dwight D. Eisenhower. The American Dream.
