Actor Cha Tae-hyun, appearing on "Whenever Possible," brings the set to laughter by properly poking at the comedy pride of "national host" Yu Jae-seok.

SBS variety show "Whenever Possible," which has established itself as a Tuesday entertainment powerhouse in terms of viewership ratings and OTT buzz, released on-site stills ahead of its August 25 broadcast featuring hosts Yu Jae-seok and Yoo Yeonseok along with guests Cha Tae-hyun and Jin Ki-joo visiting spare moments in Gwangjin-gu, Seoul.

On this day, the ignition for Cha Tae-hyun's "Yu Jae-seok catching" started with Yoo Yeonseok's respect for acting. When Yoo Yeonseok praised the two by saying, "Comedy acting is the hardest, but the older brothers pull it off," Cha Tae-hyun drew a line, saying, "You shouldn't compare Jae-seok hyung and me." He then delivered a critical blow that scratched Yu Jae-seok's pride, adding, "Jae-seok hyung just does it recklessly, whereas I do systematic, analytical acting."

Cha Tae-hyun's teasing did not stop there. On this day, he kept Yu Jae-seok on edge by raising his blood pressure with casual remarks and then acting completely innocent. In particular, he slyly asked a young fan of Yu Jae-seok whom they met on set, "He's not that great in person, right?" and induced the child to nod with a smile, making Yu Jae-seok bristle.

It is said that at Cha Tae-hyun's non-stop teasing, Yu Jae-seok ultimately cried out to Jin Ki-joo sitting next to him, "Ki-joo, please teach Tae-hyun a lesson," sending the set into a burst of laughter.

The delightful tiki-taka of Yu Jae-seok and Cha Tae-hyun, who boast a feuding chemistry whenever they meet, will air on "Whenever Possible" at 9 p.m. on Tuesday, August 25.
