SISTAR Charms the Cast of "1 Night, 2 Days" with a Surprise Appearance

Girl group SISTAR made a special appearance on the latest episode of KBS2TV’s “1 Night, 2 Days.”

On the July 20 episode of the well-loved variety show, the cast members were joined by a number of teachers from schools around Korea. Together they went on a special summer trip, and the experience was wrapped up with an entertaining talent show. 

Right before kicking off the talent show, SISTAR entered the room as guest judges to cheer up the teachers, some of whom had never before met a girl group in real life. 

While most teachers locked their eyes on the girls in awe, one teacher attempted to stay true to his occupation and said, “Your outfits are a bit inappropriate,” evoking laughter with the witty comment.
