HaHa flared up at Suzy and J.Y. Park on the latest episode of 'Running Man'.

The cast was given the mission to travel around various locations in the city of Gwangju, playing games and collecting hints for the final mission.

At one of the locations, in order to earn the right to eat, the cast would have to answer correctly a series of yes/no questions. In response to multiple wrong answers from the cast, the difficulty level was lowered with the easy question, "'Know thyself' is a famous quote from Shakespeare". This was an incorrect statement; 'know thyself', in fact, dates from the time of the ancient Greeks.

Although the majority of the cast held up (correctly) 'no' as their answers, only Suzy held up the incorrect 'yes' sign, earning the ire of her fellow teammates.

Attempting to cover up for her mistake, fellow guest Ji Jin Hee said, "Her gag sense is superb". HaHa would have none of it, however. Pointing at the screen, he yelled, "JYP hyung! Get her to study a little!"
