While watching Lee Jung Jae's slapping scene on the show, D.O said, "I've been slapped before, and at the moment, I laugh if it hurts too much.  I wondered if he caused an NG because he was too taken aback from the pain.  I was slapped by Kim Hee Won [in the movie 'Cart'].  I bowed my head down because I was worried I'd cause an NG.  But to tell the truth, it is harder for the person doing the slapping. It was a really good experience."
