The variety show has been doing a '1 Hour Prior' special for past couple weeks and this time around, Yoo Jae Suk had to face his fear of heights. He was escorted to a mysterious location while blindfolded and once he took the blindfold off, he immediately became flustered and constantly asked, "What is this?"

The comedian was given the task to clean and sweep up a long bridge which stood at the height of 100m (328 feet) and length of 200m (656 feet). The challenge at times became too stressful which made Yoo Jae Suk constantly run back to the start point. Check out all the clips below.

Do you think you could accomplish this without any problem?
