On the show, both members were asked if 'Knowing Brothers' was their first variety show appearance since being discharged from the military. Changmin revealed that it was actually their third variety show and the first one was filmed with Yoo Jae Suk. To this, Super Junior's Heechul bluntly asked, "Is it because you like Jae Suk hyung more than Ho Dong hyung?" To this, Changmin nodded and was asked to choose between the two MCs. He chose Yoo Jae Suk without a second of hesitation.
Changmin explained his reason with, "I saw...I saw Ho Dong hyung hitting Soo Geun (Lee Soo Geun) hyung," as he impersonated Kang Ho Dong. After hearing this, Kang Ho Dong became flustered and gave up while saying, "Okay, you guys do whatever you want." He later joked to Changmin, "Nevertheless, you better become very successful if you're going to make me look like this. Step on me and stand tall," that made everyone laugh.
