话说我最近在追的几部美剧都是sitcom为主，不动脑，笑一笑二十分钟就完事，比drama那些要轻松太多。
TBBT最终季第23集的#CLP，Lorre大神居然发的就旧贴，还是一则笑话。太简单了，不翻译了，说几个知识点：
moth，飞蛾，所谓飞蛾扑火，提示：这是一个冷笑话。
dentis牙医，psychiatrist（psychologist，俚语叫shrink）心理医生，在美国，医生、律师长期并列最受欢迎职业榜单，收入、社会地位很高，因此也有无数热门的医务剧、律政剧，广受美国人民喜欢。
其他医生还有：surgeon外科医生，gynecologist妇科医生（还记得Friends里面Ross去医院看怀孕同性恋前妻时候说的吗，OBGYN--OBstetrics产科+GYNecologist妇科，也就是妇产科），pediatrician儿科医生，internist内科医生，otolaryngologist耳鼻喉科医生，而physician则是医师通称。医学英语又是一门新天地，我这里就不展开说了。。。水平有限- -||
PUNCH LINE：
我们来看看维基百科是怎么解释的：
A punch line (or punchline) is the final part of a joke, comedy sketch, profound statement, or story, usually the word, sentence or exchange of sentences which is intended to be funny or to provoke laughter or thought from listeners. Few punchlines are inherently funny out of context, but when a comedian sets up the premise and builds up the audience's expectations, the punch line can function as the climactic part of the act. Punch lines generally derive their humor from being unexpected. The classic stand-up punch line sound is a sting (erroneously called a rimshot) on drums.
