This 65 year old black comedy still hits the spot today. Lemmon plays a likeable minion in an enormous 1960s office building who is bullied into allowing his superiors borrow his bachelor apartment for illicit sexual liaisons. Complications ensue when he falls for one of the girls who is being led along by a senior manager. The the story is very black and very clever. The acting is terrific and the period setting is reminiscent of some of the earlier episodes of Mad-Men.
