The April 12th broadcast of KBS 2TV's 'Happy Together 3' was met with an unexpected guest which surprised cast members and viewers. The episode featured Jang Nara, Kim Min Seo, HaHa, Taw, Ji Suk Jin, and Kim Soo Yong.

Actress Kim Min Seo, who had played the role of Queen on 'The Moon that Embraces the Sun', was questioned whether she had noticed her rise in popularity in her daily life. As soon as the actress was about to answer, the studio was silenced by a "jjik jjik" sound coming from above. The cast members were prompted to look up in shock.

MC Shin Bong Sun explained, "There's a rat," as the noise continued.

In an attempt to quiet the rat, MC�Park Myung Soo hilariously scolded, "The Queen is talking!", causing everyone on set to burst into laughter.
