Abstract
With the help of the Functional Equivalence Theory, this paper aims at summarizing suitable pun-translation methods via analyzing puns and their translations in The Big Bang Theory.
Through studying the principles of Functional Equivalence Theory, which are the equivalence of words and phrases, of sentences and structures, of sections and chapters and of writing styles, different types of pun translation from the Big Bang Theory would be discussed and analyzed. To achieve the consonance and unity of meaning and forms in pun translation of film and television programs, methods of translation based on pronunciation, construction and signification are drawn, such as literal translation, paraphrase and annotation, etc..

Since 2007, American shows “The Big Bang Theory” came into view of the Chinese audience. Characters of copious individuality, frequent comedy conflicts as well as witty and humorous dialogues attract a large number of Chinese fans. To some extent, the pun translation in this show, which is an indispensable jewel in the crown of this TV show, brings a refreshing cultural experience to the audience.
A pun is a humorous use of a word in such a way as to suggest two or more of its meanings or the meaning of another word similar in sound. Pun vests certain words or sentences a dual meaning, or oblique accusations, or an ulterior motive in a specific language environment, which enhances the vitality of language and improves the delight of implication and humor. (Lin Tingting, 2010) The traditional pun translation notion claims that puns are untranslatable unless equivalents exist in the target language or mystify pun-translation as depending on gifted talent.
