Buster Keaton in the context of "Silent Movie"

A parody is a creative work designed to imitate, comment on, and/or mock its subject by means of satirical or ironic imitation. Often its subject is an original work or some aspect of it (theme/content, author, style, etc.), but a parody can also be about a real-life person (e.g. a politician), event, or movement (e.g. the French Revolution or 1960s counterculture). Literary scholar Professor Simon Dentith defines parody as "any cultural practice which provides a relatively polemical allusive imitation of another cultural production or practice". The literary theorist Linda Hutcheon said "parody ... is imitation, not always at the expense of the parodied text." Parody may be found in art or culture, including literature, music, theater, television and film, animation, and gaming.

The writer and critic John Gross observes in his Oxford Book of Parodies, that parody seems to flourish on territory somewhere between pastiche ("a composition in another artist's manner, without satirical intent") and burlesque (which "fools around with the material of high literature and adapts it to low ends"). Meanwhile, the Encyclopédie of Denis Diderot distinguishes between the parody and the burlesque, "A good parody is a fine amusement, capable of amusing and instructing the most sensible and polished minds; the burlesque is a miserable buffoonery which can only please the populace." Historically, when a formula grows tired, as in the case of the moralistic melodramas in the 1910s, it retains value only as a parody, as demonstrated by the Buster Keaton shorts that mocked that genre.

Silent comedy is a style of film, related to but distinct from mime, developed to bring comedy into the medium of film during the silent film era (1900s–1920s), before synchronized soundtracks that could include dialogue were technologically available for the majority of films. While silent comedy is still practiced today, albeit much less frequently, it has significantly influenced modern comedic media.

Many techniques used in silent comedy were borrowed from vaudeville traditions, with many silent comedy stars, such as Buster Keaton and Charlie Chaplin, getting their start in vaudeville. Silent comedies often place a strong emphasis on visual and physical humor, frequently utilizing "sight gags" to convey stories and entertain audiences. These gags often involved exaggerated forms of violence, a style that became known as "slapstick". Classic examples of slapstick comedy devices include the "pratfall," slipping on a banana peel, getting soaked with water, and having a pie thrown in one's face.

A disguise can be anything incognito which conceals one's identity or changes a person's physical appearance, including a wig, glasses, makeup, fake moustache, costume or other items. Camouflage is a type of disguise for people, animals and objects. Hats, glasses, changes in hair style or wigs, plastic surgery, and make-up are also used.

Disguises can be used by criminals, terrorists, secret agents and special forces operators seeking to avoid identification. A person working for an agency trying to get information might go "undercover" to get information without being recognised by the public; a celebrity may go "incognito" in order to avoid unwelcome press attention. Protests often feature people dressed in humorous costumes while political publicity stunts and pranks sometimes employ disguises and imposture. In comic books and films, disguises are often used by superheroes, and in science fiction they may be used by aliens. Dressing up in costumes is a Halloween tradition.

A bathtub, also abbreviated as bath or tub, is a container for holding water in which a person or another animal may bathe. Modern bathtubs can be made of thermoformed acrylic, porcelain-enameled steel or cast iron, or fiberglass-reinforced polyester. A bathtub is usually placed in a bathroom, either as a stand-alone fixture or in conjunction with shower plumbing.
