In SBS Running Man', the Parallel theory is revealed between Yoo Jae-Suk and Yoo Seung-ho. The recent recording was the signature relay Grim mission of Running Man'. Previously, the members showed incredible unity with all kinds of tricks when they made a Grim mission every time they made a Grim mission, but this time, the upgraded contest was held by combining the character quiz and Grim. Yoo Jae-Suk and Yoo Seung-ho came out as the first runners of the relay Grim. Yoo Jae-Suk has always been embarrassed by showing a unique style every time a Grim-related mission is given, but this time he appealed to me with confidence that "I only draw points" and "I have to understand my style." Yoo Seung-ho was also confident with a smile, and Yoo Su-bin cheered, saying, "Yoo Seung-ho is from the gold medal of the art competition." After the start of the full mission, when various stars were presented, the two men burned their art souls. Yoo Jae-Suk expressed all the characters in short and bold points, while Yoo Seung-ho shocked everyone by creating half-person characters. When the unexpected Grim appeared, the members laughed at the Parallel theory about the Grim ability of the Tuyu Brothers, saying, "I think they are going through something" and "I have to look at it as a magic child." The identity of the extraordinary work of 'Tuyu Brothers' can be seen in Running Man' broadcasted at 6:15 pm on this day.
