Singer Huh Gak successfully pranked Apinks Jung Eun Ji on the April 23 episode of MBCs Secretly Greatly.
The premise of the prank was that Huh Gak was preparing for his very first musical by taking lessons from a teacher. He asked his very close friend Jung Eun Ji for some tips on doing musicals, and she decided to watch over him at his lesson.
Before his lesson officially began, Jung Eun Ji was giving him some advice when a cleaning lady suddenly came in and starting dissing him under her breath. Upon hearing her insults, Jung Eun Ji loudly played the piano to prevent him from listening to her and even locked the door as soon as she left.
