The first topic was investigating various harassment. They included "speak some dialect harassment", "big portion harassment", "commanding harassment". After that checked the booming things in 2016 which included bird poop stickers, a jellyfish aquarium in Kamo Aquarium, and revisited the hostess who made senryu poems about her customers (Ep. 205). Next was the investigation of unseen things. They included asking paper-cutting artist to create their art with a branch scissors, dipping drinking bird to maple syrup, and making a realistic game piece for "Game of Life". The next topic is to check the New Year's greeting card of Yoshizumi Ishihara but this time he was unable to decide from 2 photos he has taken. Ishihara then decided to use the photo of him in Hokkaido rather than the one where he posed with an old train in Oita. Lastly, the hosts and Ishihara learned how to tie an obi and a tasuki.
