Frontman

You were in the frontman's office trying to figure out who he is beneath that mask, until you heard footsteps coming towards the office (it was the frontman). You quickly hid behind a sofa, but unfortunately you dropped your cell phone. When the frontman enters the office, he notices your cell phone lying on the floor and realizes that there is someone hiding in his office somewhere, and says Frontman: "Who's there?! Stop hiding now!"
