Numerous running jokes and themes develop throughout the series. Chief among them are the class and familial conflicts among Frasier, Niles, and Martin. The two sons, who possess 'fine' tastes, 'intellectual' interests and rather high opinions of themselves, frequently clash with their more blue-collar, down-to-earth father. A running theme, particularly in the early seasons, is Frasier's and Martin's difficulty in reaching an accommodation with each other and in sharing an apartment. Despite being similar in personality, interests, and sensibilities, the relationship between Frasier and Niles is no less turbulent. Despite their mutual love of sherry, opera, and ballet, they are constantly victims of intense sibling rivalry, their jealousy of each other and petty attempts at one-upmanship (which frequently result in chaos) drive many of the plots. Other developing storylines include Niles' growing love for Daphne (of which she remains unaware in the early seasons, despite its increasingly obvious nature) and the breakdown of his marriage to the never-seen Maris (a take-off from its parent series, "Cheers," in which Norm's wife, Vera, was often talked about--and even heard--but never seen), Frasier's search for love in his own life, and the various attempts of the two brothers to gain acceptance into Seattle's cultural elite.
Structurally, many episodes center around misunderstandings or elaborate lies which multiple characters are forced to "play along" with in order to conceal the truth. Frasier also featured many "once-a-year" plot devices, such as an appearance by Frederick, Lilith, or Bebe. Season finales sometimes took the form of a "two part" special that was concluded as the series premiere the following season. 这是美国历史上最伟大的喜剧之一。这一切都来自一位名叫弗莱泽的波士顿的精神病医生,在结束了自己两段不幸福的婚姻后,心灰薏冷的返回了自己父亲的老家西雅图,父亲从英国请来的私人女健康顾问以及同为精神病医生的弟弟共同住进了一所公寓,弗莱泽医生在当地的广播电台找到了工作,充当一个类似心理咨询栏目的主播,在这个岗位上,他可以借着电波为人们解决心理上的难题,也因此解释了很多朋友,也被迫天天面对着“热情”的女节目制作人。同时,作为喜剧,弗莱泽的后院也不会安然无恙。他的警察父亲倒不是最麻烦的,麻烦的是他弟弟深深暗恋着女健康顾问,经过弗莱泽和弟弟六年的努力,二人终于开始交往,种种复杂的情况带来了无穷的笑料。
