Avatar: The Last Airbender Season 3 Episode 17 : The Ember Island Players
Sokka discovers that the Ember Island Players, a Fire Nation theatre group, is debuting a play based upon their adventures. The play turns out to be Fire Nation propaganda, and although the audience enjoys the play, Aang and his friends are embarrassed by the inaccurate and exaggerated portrayals of themselves (with the sole exception of Toph, who is amused by her depiction as a large muscled man who employs a primitive form of sonar by yelling at everything). In context, the play also serves as a concise summary of Aang's entire journey throughout the show. The play ends with the Fire Nation winning the war and the Firelord killing the Avatar, which triggers a standing ovation from the audience and fright from Aang.
