Surreal humor was made using surrealism, an art movement of the 20th century. French and Belgian artists started it. They depicted illogical scenes while creating methods to allow the unconscious mind to express itself. The movement itself was foreshadowed by English writers in the 19th century, most notably Lewis Carroll and Edward Lear. The humor in surreal comedy comes from performing in a manner that contradicts audience expectations, emphasizing the silliness and low chances of the situation occurring, so that the humor is created from uncertainty that is separate from a logical analysis of the situation.
