Season 18, Episode 9 - "The Flash"
Kenny uncovers an instant camera in the station basement and decides to start taking photos of the workplace for a “memories” board in the break room. Bulldog, Gil and Denise are soon getting sick of constantly being “flashed” by Kenny’s camera, and decide to hide it from him. When it is learnt that a scandalous celebrity secret may have been inadvertently exposed in one of Kenny’s photos, they will do anything to get the camera back. Unfortunately, Roz has just given it away to a charity, along with everything else from the basement that remains unused.
