Lee Kwang Soo Appears As Guest in Yoo Jae Suk & Yoo Yeon Seok's New Variety Show

On April 23, SBS' new variety show "Whenever There's a Moment" released a new episode where Lee Kwang Soo appeared as a guest.

Before he arrived at the scene, the program's original hosts Yoo Jae Suk and actor Yoo Yeon Seok, exchanged words about him.

The "You Quiz on the Block" host asked the drama star, "Isn't Kwang Soo signed under the same agency as you?" and funnily added, "Is his appearance on this show just a 'same agency privilege'? That's not quite the trend these days, you know."

Yoo Jae Suk Complains to Lee Kwang Soo For Declining Appearing in 'Running Man'

Just as the bickering was heating up, Lee Kwang Soo finally entered the frame exhibiting an awkward smile. That time, Yoo Jae Suk didn't miss a beat and immediately teased him, "Yah! We have been trying to get you on 'Running Man,' but you keep turning us down. Why are you making your appearance on this one when you keep declining to 'Running Man,' huh?"

Lee Kwang Soo was caught on guard by the veteran MC's sudden mention of "Running Man."

The actor-comedian interjected, "Why bring up that here?" However, Yoo Jae Suk ignored the interruption and went on, "I bet viewers will begin thinking Yoo Yeon Seok pulled some strings to get you on this program. I am getting worried now."

Continuing their iconic banter whenever they're on variety shows, Lee Kwang Soo could not help but respond loudly saying, "Nobody's going to think that! I received a lot of offers from other TV programs, okay?"

His hilarious comment made Yoo Yeon Seok and Yoo Jae Suk laugh hard.

Meanwhile, during the 700th episode of "Running Man," the mainstays expressed their honest opinions and mentioned Lee Kwang Soo and Song Joong Ki as celebrities who want to appear again on the show.

Since the two were former members of the program, it will be a great feature to see them back in "Running Man."
