One of the five skits was a guy who wanted to (had to?) teach Tea Ceremony in his home, but he misunderstood the ritual. For example, he swung the cup around his body three times, instead of rotating it. Because he used something else instead of powdered tea (beans??), it didn't foam enough, so he had to add laundry soap. Fortunately, his "students" didn't understand the ritual, either, and they imitated his teachings and praised the tea. I think that's how it went.
We attended this event with Muyan, Masako, Yoko, Emi, and Sari. A number of people slept through the show, but most of the audience were laughing, so I guess it was in fact comedic.
