Two of South Korea's most-loved athletes, swimmer Park Tae Hwan and gymnast Son Yeon Jae, guested on the latest episode of 'Running Man' where they eagerly participated in the competition. Son Yeon Jae also took the opportunity to settle a past score with cast member HaHa.

When asked during the opening which member she would like to rip the nametag off first, she answered "HaHa" without hesitation. When prodded why, she replied, "I saw HaHa once when I was younger, and he refused to give me an autograph," she revealed.

When HaHa couldn't think of the memory, Son Yeon Jae continued, "It was during elementary school, and we truthfully were being somewhat annoying," she said. "HaHa looked over at our direction and said, 'you guys already got my autograph'."

A desperate HaHa then tried to make amends, but was blocked by 'bodyguard' Yoo Jae Suk.
