Lee Kwang Soo made viewers laugh as he carried out the ultimate 'betrayal'.

The actor was a guest on 'Gag Concert' on the 13th carrying out the role of�Shin Bora's new boyfriend in the show. In the segment, she requested that he show her some bravery. He followed through with her request by bravely declaring, "The nation's broadcast, KBS '1 Night 2 Days'!" causing the�audience�to�burst�out in laughter.

The 'betrayal' stemmed from the fact that Lee Kwang Soo is a permanent member of 'Running Man', which competes for ratings at the same time that '1 Night 2 Days' does. As his image in the show is the 'betrayer giraffe', he made fans of both shows laugh with his brave 'betrayal'.
