One day, when Sokka came crashing through a window of Macmu-Ling's haiku class and accidentally apologized in the form of a haiku, she greeted him with a somewhat badmouthing haiku in which she called him a "remarkable oaf", thus engaging them in a haiku duel. After an exchange of three haikus each, Sokka managed to win the poetry duel and Madame Macmu-Ling left the stage in defeat. However, when he recited his victory haiku, Sokka made a crucial error by using one too many syllables, for which he was abruptly thrown out of the room.
