Satire (from Latin satira, "medley, dish of colourful fruits") is a technique used in drama, fiction, journalism, and occasionally in poetry, the graphic arts, the performing arts and other media in which the artist or author draws out societal or religious criticisms through use of other literary devices. Although satire is usually witty, and often very funny, the purpose of satire is not primarily humour but criticism of an event, an individual or a group in a clever manner.

Adair Welcker, Poet
THE Swan of Avon died--the Swan
Of Sacramento'll soon be gone;
And when his death-song he shall coo,
Stand back, or it will kill you too.
Ambrose Bierce~
