The first topic was an investigation of towns and cities in Saitama Prefecture. It included Warabi City which was originally planned to be combined with Kawaguchi City but the Kawaguchi citizens disliked the proposed new name and Iruma City citizens which had a tea naming dispute with neighboring Sayama City. The Iruma citizens were also tired of being associated with Illmania (Ep. 125). After that, they checked on various "need to know" information. It included "how many eggs you can eat a day" and "how Saito and Watanabe family name variations were born from writing mistakes". The hosts chose two topics about tap water and "half of year was gone" but the staff did not prepare any materials, much to Matsuko's anger. They then checked on the top 5 vegetable with best nutritional value. For the last topic, they checked on misleading things such as a small zoo called "Banana Crocodile Park" which was famous for its lesser panda and a famous ramen shop that did not appear in navigation systems.
