I'll nominate Arms and the Man by George Bernard Shaw.
Arms and the Man is a comedy with typically brilliant Shavian wit combined with very serious themes. Among them are the futility of war, hypocrisy, self-delusion, and stereotyping. Most satiric comedy has a dark edge and this play is no exception.
It is in the public domain and free from Project Gutenberg.
