隣のクラスの担任のばんの先生が、ある日突然頭をそってきた。生徒たちにハゲと冷やかされるばんの先生。そんなばんの先生がある日気球に乗り飛んでいってしまう。その後のことは誰も知らない。

One day out of blue Prof. Banno of next class came to school with his hair shaven. Students made fun of his baldhead. Prof. Banno flew in a hot-air balloon the other day. Nobody knows anything about him afterwards.
