Nichkhun dissed himself through an 'SNL Korea' skit that brought up his drunk driving incident.
One of the 'SNL Korea' skits featured 2PM members talking to their past selves. Taecyeon told his past self to get used to farming equipment and how to use old style kitchens (referring to 'Three Meals A Day'). When it came to Nichkhun's turn, his past self asked him if he would be able to survive in Korea even though his Korean was not that great. Nichkhun told his past self to learn a bit more Korean, and then said he would get popular soon. When his past self then expressed his desire to buy a car, Nichkhun dove in screaming, "No! No. Don't drive." He then added, "Drink at home. And if you have to drink outside, always call someone else to drive for you."
He then added that if he did make a mistake, he had to reflect upon his actions and the public would eventually forgive him.
