This time, Heechul got to make a question for guessing time since he became a guest with Super Junior. The other Super Junior members teased him so much that Heechul could not stand it.
This time, Shindong confessed that he hated Super Junior members, especially Donghae, back in the past because they tended to wear his clothes without his permission.

Episode 118 – Park Jin-young (JYP), Got7
To imagine Got7 together with their own senior and CEO, JYP in the same variety show is funny enough though. But seeing them together in Knowing Bro where they are all the same age friends? Even more hilarious!
Jinyoung became the representative to receive a punishment that was to get water splashed. The others suggested JYP splash him but then changed to the leader JB. Instead of splashing Jinyoung, JB splashed the others while Jinyoung only got splashed a little.
Jackson revealed that he was confused by the Korean age system such the term of ‘fast birth’ (in Korea, anyone who was born in the first 2/3 months of the year is considered older than the ones who were born in later months). He said that he figured that JB was the same age as him, only being older by less than 2 months, after 1.5 years after they first met.
