Last week, the cast of 1 Night 2 Days became the girls of 2NE1 for a hot performance of Fire. The most memorable transformation was definitely Kim C's; he impersonated Sandara Park and wowed the crowd with his hilarious costume. On today's episode of the show, the guys talked about the episode last week. Kim C said, "I think I did something wrong to her (Sandara). I'm really sorry for it." He continued, "I got to know 2NE1 through this experience and I really love their music. They're so charming." Lee Soo Geun then joked, "It's been a year since they've debuted..."

Although Kim C is pretty late in discovering the fierce foursome, 2NE1 just gained another fanboy fanman! Re-watch the hilarious performance from last week's episode below. http://www.youtube.com/watch?v=Z_r-FUUlEQA
