IU showed off her version of Ga In's�dance on the 'Go Show', surprising everyone on set.

She announced, "I'll do a wave to commemorate becoming 20 years old." She then danced to Brown Eyed Girls' "Abracadabra", going down onto the floor with spread knees and performing a wave.

The move shocked the panel, and IU couldn't help but burst out in laughter at herself, stopping the dance there.

Suzy also showcased her Taekwondo skills on the same segment, breaking four boards, and earning applause.
