Funny song - Gishoka

…The name originates from the section on humorous poems in Volume 19 of the Kokinshu, which contains 58 poems, but it comes from a term used in Chinese poetry. Humorous poems were already found in Volume 16 of the Manyoshu, such as "Humorous Songs" and "Laughing Songs," and this poem belongs to that genre. In the Kokinshu, the poem "We came to view the plum blossoms, and the nightingale, singing "One by one, I am disgusted" depicts a third person arriving when a plum blossom (female) and a nightingale (male) are meeting, and the nightingale sings "Hitotoku, hitoku" to express its disgust. The poem "I asked who the owner of the golden yellow clothes was, but he didn't answer, because he was silent and the gardenia-colored clothes" is based on the interest of a hanging word.
