Lee Soo Geun called SISTAR's Bora an ahjumma (a term reserved for older and married women).
Bora and Soyu were guests on 'Lee Soo Geun and Kim Byung Man's High Society', and were said to have been high-spirited for the entire filming period.
However, because of the slippery ground due to the rain, the MCs advised the girls to be careful. Taking the advice, Bora tried to jog as carefully as possible even with the timed mission.
Her attempts to jog carefully while trying to be fast apparently ended up looking quite comical as Lee Soo Geun couldn't help but laugh, dubbing her jogging 'ahjumma jogging'. He teased, "You're a female idol, so how can you do this like an ahjumma!" and imitated her 'ahjumma jogging', causing the entire set to laugh.
The episode with SISTAR's Bora and Soyu will air on the 8th!
