In Running Man', Ji Suk-jin was the first to be found out by a lie.
In the SBS entertainment program Running Man' broadcasted on the afternoon of the 26th, Ji Suk-jin was embarrassed by failing to plan to deceive Haha.
The final mission was to find a real grandchild in a situation where each other's existence was unknown; Haha found a new hint and the hint read: 'Radio DJ is not a real grandchild.'
At this time, Ji Suk-jin appeared and Ji Suk-jin dragged Haha to a quiet place and whispered, "I am actually a real grandson." Haha, who already knew that Ji Suk-jin was not a grandson, was furious.
In the unexpected reaction of Haha, Ji Suk-jin was embarrassed and laughed, "If you do not believe it, you do not hear it," and "I do not have a place to rely on now."
