The cast had to guess what Hongki's IQ score was in order to receive a snack. When given the question, they thought about all the mistakes Hongki has made since the start of the show. As a result, the cast jokingly started to guess in the lower range between 30 to 100. Comedian Park Sung Kwang eventually guessed it correctly which was 134.
This answer, however, made the rest of the cast doubt and protest as they couldn't believe it. Afterward, Hongki explained that he received the score when he was in an elementary school and was even told by many that he was a gifted child.
