Parody makes fun of an original work in a humorous way by portraying the genre in a self-conscious manner. Self-parody involves artists using their own work for parody. Parody originated in ancient Greece where poets would alter wording in poems to make them absurd and entertaining. In the 17th century, authors like Ben Johnson and John Dryden expanded on parody by turning works into other meanings than originally intended. Now, parodies are common in movies and TV through satirical references that add to their comedic genres.
