The Shrimp Cover - S1.E9

The morals officers accidentally expose a vice squad undercover operation. After Mickey overhears a phone conversation, which says that someone is going to be 'whacked' (i.e., transferred or fired) for the mishap, everyone is afraid for their jobs. It later turns out that one of the vice squad undercover cops was crooked and exposed the operation. As the morals officers watch a TV report about the crooked cop's arrest, a cleaner arrives to say that someone called to have the squad room's floor 'waxed'.
