A humorous imitation of another, usually serious, work. It can take any fixed or open form, because parodists imitate the tone, language, and shape of the original in order to deflate the subject matter, making the original work seem absurd. Anthony Hecht’s poem "Dover Bitch" is a famous parody of Matthew Arnold’s well-known "Dover Beach." Parody may also be used as a form of literary criticism to expose the defects in a work. But sometimes parody becomes an affectionate acknowledgment that a well-known work has become both institutionalized in our culture and fair game for some fun. For example, Peter De Vries’s "To His Importunate Mistress" gently mocks Andrew Marvell’s "To His Coy Mistress."
