The TWICE members had so much fun on a 'Hidden Camera' moment where they scramble after seeing their manager walk out of the room during a recent broadcast on Naver's 'V'.

"Our manager just walked out... Shall we do a 'hidden camera'?" the girls whispered unable to hide their excitement.

"Shall we hide his cell phone?" Then one of the girls mentioned, "It's right here."  "Wait, there's one here too," "No, his phone is over there," as they found out the manager had a total of three phones sprawled across the room.

The members then decide to hide the cell phones trying to come up with a good plan.

Watch how they laugh hysterically after they fail the prank in the funny video clip.
