The first topic was an investigation of "battle point" between Japanese people. They interviewed 100 people to determine whether people mostly wash their bath towel after one use or not. In the end 55% said that they wash their towel every day. They later watched an investigation about barbers. The number of barber shop was decreasing and the average age of barbers is about 63 years old. But, recently "New York barber boom" helped to increase the popularity of barbers again. A barber later came to the studio and gave Murakami a 7:3 hairstyle. For the next topic, they watched a video on how various business find a way to survive. For example, a futon shop usually rent their futons and gained more profit than selling them. The last topic was a deep investigation about fart, ranging from its contents to a man who made a lot of money due to his ability to fart for quite a long time. (Source: MyDramaList)
