Five-Seven-Five Society

The 5-7-5 Society is an organization of young women who specialize in the art of poetry, with a focus on Haiku. Taught by the strict and disciplined Madame Macmu-Ling, only the wealthy young ladies of the upper echelon of families in Ba Sing Se are allowed to join the group. The society even has a guard who throws out people unworthy of the art. They have poetry meetings, in which haikus are recited by each member. In addition to practicing haiku, the girls also enjoy tea parties, garden parties and plain old parties.

When listening to the poetry through a window Sokka is accidentally kicked through the window by an unruly Ostrich Horse onto the stage. He apologizes, accidentally speaking in haiku form which impresses the young ladies and irritates Madame Macmu-Ling. Sokka further impresses the group by throwing out a few more witty haiku, outdoing Madame Macmu-Ling herself. After getting slightly too cocky, Sokka mistakenly adds a sixth syllable to his last haiku, and is literally thrown out of the building.
