Comedy is the use of humor in the performing arts. It also means a performance that relies heavily on humor. The term originally comes from theater, where it simply referred to a play with a happy ending, in contrast to a tragedy. The humor, once an incidental device used to entertain, is now an essential aspect of a comedy.
A recognised characteristic of comedy is that it is an intensely personal enjoyment. People frequently fail to find the same things amusing, but when they do it can help to create powerful bonds.
