Don't belittle the supporting speaker; he has to take charge of the performance's rhythm and ask questions on the audience's behalf. According to the old rules, he is usually a senior in the profession, or even the master of the main speaker.
可別小看這「捧哏的」，他要負責掌控表演的節奏，也代表觀眾發問，若按老規矩，他往往是資深前輩，甚至是「逗哏」的師父。
