In the 20th century the term Parody Movie was the description of a funny and humorous spoof film. Its comical humor would make fun of existing popular movies, or sometimes even movies that were not so popular, but they where done in such comical ways that the audience did not need to know what the film's humor was based on. They where guaranteed to laugh and laugh and laugh and laugh and laugh, then stop laughing, groan, then resume laughing at things that were not meant to be laughed at.
